The handle 53 can be secured to the leg in any suitable manner and as illustrated the handle has a threaded end 54 which threadably engages a hole 54&#39; in the leg 9 for removably securing same to the frame 8.  
  The apparatus 1 is provided with means which cooperate with the clamping structure 7 which is operable to perform certain assembly operations on the cable shield bond 2 and the cable 4, such as aligning, fastening and cutting operations. Any suitable means can be employed and as illustrated, the member 15 is provided with suitable guide means which is illustrated as an axial bore 55 extending through the bushing 23 co-axial with the bore 25 and the bore 46 and generally normal to the surface 29. A plurality of devices or tools are provided for effecting the aligning, fastening and cutting operations with each having a shank portion 59 of substantially the same diameter and receivable through the bore 55 with each of the devices having a free end suitably shaped to perform the various assembly operations in sequential steps.  
  In the particular form shown, six devices are provided and are numbered 60, 61, 62, 63, 64 and 65. The device 60 is a punch and has an end 67 sized and shaped to fit snugly in the bore 46 to form a punch arrangement operable to form holes upon application of force, such as with a hammer to the other end of the device 60. As illustrated, the end 67 is concave to provide a cutting edge. The device 60 and the devices 61, 62, 63, 64 and 65 are provided with handle members 68 on the free ends thereof, which are illustrated as enlarged and knurled diametral portions, to facilitate withdrawal of the devices from the bore 55 after use. The device 61 is an aligning tool and has an end 69 with a two-step decreased diameter portion including the smaller diameter portion 70 and the larger diameter portion 71. The device 62 is a forming tool and has an end 73 suitably formed or shaped to deform or peen certain portions of the cable shield bond upon application of force to the handle end thereof. The device 63 is an aligning tool having an end 74 which preferably has a two-step reduced diameter portion which includes a small diameter portion 75 on the end thereof and a larger diameter portion 76 between same and the shank of the aligning tool 63. The device 64 is a forming tool having an end 78 operable to deform or peen certain portions of the cable shield bond upon application of force to the other end of the forming tool 64. It is to be noted that the tools 62 and 64 are similar with each having a shoulder 73&#39; and 78&#39; respectively between the forming ends 73 and 78 and the shanks to form the peen areas. The device 65 is a driving punch having a work engaging end 79 adapted to engage a fastener for securing the cable shield bond to the cable sheath as described below.  
  The cable shield bond 2 in the illustrated structure includes a contact structure 81 comprised of a pair of opposed contact members 82 and 83 with the contact member 82 having a tubular shank 84 projecting therefrom and receivable through an opening 85 through the contact member 83. The cable shield 3 is interposed between the contact members 82 and 83 and has a through opening 86 receiving the shank 84 therethrough wherein the contact members 82 and 83 are secured together in electrical contact and clamping relation to the cable shield 3. As illustrated, the free end of the shank 84 is peened or otherwise formed to have a peened portion 87 overlying the outer disposed surface of the contact member 83 to secure same in contacting relation to the cable shield 3. The cable shield bond 2 is also provided with a clamping structure 88 which is adapted to secure a pair of opposed sealing members 89 in sealing engagement with the cable shield 3 peripherally outwardly of the contact members 82 and 83 preventing the entry of air and moisture to the electrical contact areas of the contact members 82 and 83 and the cable shield 3. As illustrated, each of the seal members 89 has an opening 94 therethrough that is positioned in axial alignment with an axial opening 90 through the shank 84. The clamping structure 88 includes a pair of opposed clamp members 91 and 92 with the clamp member 92 having a shank 93 projecting therefrom and being receivable through openings 94 through each of the seal members 89 and the opening 90 and an opening 95 through the clamp member 9l. Preferably. the shank 93 is hollow or has an opening 93 adjacent to the free end thereof and is adapted to be peened or otherwise formed to have a peened portion 96 overlying the exterior surface of the clamp member 91 and secure the seal members 89 in sealing engagement with a cable shield 3. It is desirable to support the cable shield bond 2 on the cable 4 and in this regard a tongue 98 is cut or otherwise formed on the cable sheath 6 and projects therefrom A hole 99 is cut or otherwise formed through the tongue 98 and the cable shield bond 2 is suitably secured to the sheath 6 such as by having a drive screw 100 extend through the hole 99 and into the hollow portion of the shank 93 and is suitably driven into the shank 93 to secure the tongue between the exterior surface of the clamp member 92 and the head of the drive screw 100.  
  The present invention is more fully understood by a description of the operation thereof. After the splice is effected between the opposed cable ends, a tongue 101 preferably is cut or otherwise formed on the cable shield 3 and the tongue 98 is suitably formed on the sheath 6 wherein the tongues 98 and 101 are arranged one over the other. The apparatus 1 is mounted on the cable 4 by inserting the tongue 49 between the cable shield 3 and the wires 5 or wrapping thereof and the clamp 52 secures or anchors the handle 51 and thereby the apparatus 1 to the bundle of wires 5.  
  The tongue 98 and the tongue 10] of the cable shield 3 are placed on the work surface 29 and the member 15 is screwed down wherein the end 19 is in engagement with the tongue 98 clamping the tongues between the end 19 and the work surface 29. It is to be noted that a wrench (not shown) such as a ratchet wrench may be used to screw the member 15 down by having the wrench engage the flats 20 and that because the shank 24 is rotatably received in the bore 25 of the sleeve 26 portions of the cable shield bond and the cable 4 can be clamped between the surface 29 and end 19 without the end 19 turning against same. The punch 60 is inserted through the bore 55 with the end 67 thereof engaging the tongue 98 and upon application of force, such as with a hammer, to the other end of the punch 60 the hole 99 and the opening 76 are formed through the tongues 98 and 101 respectively. The tongue 98 can now be secured in an out of the way position, such as by bending same back over the cable sheath 6 and securing same with a piece of tape 102 in the out of way position. To eliminate the need for screwing the member 15 in an out sufficient distances to provide clearance, the lock member 35 may be released after each operation to permit hinging movement of the frame 8 relative to the anvil 28 to provide work clearance and upon completion of an assembly operation, the lock member 35 can be reinserted in the slots 33 and 34 wherein the apparatus 1 is ready for the next operation. The shank 84 of the contact member 82 is inserted through the cable shield opening 86 and is placed on the work engaging surface 29. It is to be noted that the exterior surfaces of the contact member 82 and 83 and the clamp members 91 and 92 are generally convex wherein the concave surfaces of the anvil 28 and end 19 provide increased engagement and help hold the contact members and clamp members in clamped engagement during the assembly steps. The device 61 has the smaller portion extending into the opening 90 and the contact member 83 is positioned on the larger diameter portion 71 by receiving same through the opening after the device 61 is inserted through the bore 55. The device 61 holds the contact members 82 and 83 in alignment while the member 15 is screwed down to clamp same between the work surface 29 and the end 19. After clamping, the device 61 is withdrawn and the device 62 is inserted through the bore 55 with the device 62 having the end 73 suitably formed with the shoulder 73&#39; to deform or peen the end of the shank 84 over thereby forming the peen 87 and securing the cable shield 3 between the contact members. Peening is effected by applying force to the device 62, such as with a hammer striking the upper end of the device 62 and the end 73 is sized to fit in the opening to prevent decreasing the size thereof during peenmg.  
  After peening, the member 15 is screwed out to relieve the clamping force and the lock member 35 is released to permit the pivoting movement after which one seal member 89 is mounted on the shank 93 by having same extend through the opening 94 and the contact structure 81 is mounted on the shank 93 by having the shank extend through the opening 90. It is to be noted that the shank 93 can be provided with a plurality of ribs or protuberances 105 adjacent the inner disposed surface of the clamp member 92 with a dimension slightly larger than the diameter of the opening 90 so that the ribs 105 penetrate the surface of the opening 90 to insure good electrical contact therebetween. If the ribs 105 are provided the member can be screwed in with the clamp member 92, the one seal member 89 and the contact structure 81 between the end 19 and work engaging surface to urge the shank 93 through the opening 90 after which the member 15 is screwed out the the frame 8 is released. The device 63 is inserted through the bore 55 and the clamp member 91 and the other seal member 89 is placed on the end 74 of the punch 63 by inserting the large portion 76 through the opening 95 and the opening 94 and the smaller portion 75 is received in the hollow portionof the shank 93 to align the clamp member 91 and the seal member 89 with the contact structure 8!, the one seal member 89 and the clamp member 92. The frame is pivoted and retained in non-pivoting relation by the lock member 35 and the member 15 is screwed down urging the clamp members 91 and 92 toward one another and into clamping engagement with the seal members 89 and contact structure after which the device 63 is withdrawn, which may be facilitated by use of the handle 68. The device 64 is then inserted through the bore 55 with the end 78 sized to be received in the hollow portion 93&#39; of the shank 93 and upon application of force to the upper end of the device 64, the end of the shank 93 engages the shoulder 78&#39; on the device 64 and is peened over to form the peen 96 and secure the clamp members 91 and 92 in clamping engagement to the seal members 89 and the contact structure 81. The end 78 is sized to fit in the opening 93&#39; to prevent same from becoming smaller during peening. it is important during clamping of the clamping structure 88 that the seal members be deformed sufficiently to provide a seal against the cable shield 3. In this regard, the member 15 is screwed down until about l/l6 inch of the seal members 89 extends outwardly of the peripheral edges of the respective clamp members 91 and 92. After the peen 96 is formed the member 15 is screwed out and the lock member 35 is released to allow pivoting of the frame 8 so that the tongue 89, after the tape is removed, can be moved wherein the hole 99 is in alignment with the hollow portion of the shank 93. The drive screw 100 is inserted through the hole 99 and into the hollow portion of the shank 93 after which the frame 8 is pivoted and the lock member 35 re-secures the anvil to the frame 8 and the member 15 is screwed down to hold the drive screw in place after which the device 65 is inserted through the bore 55 and upon application of force to the free end ofthe device 65, the drive screw is driven into the shank 93 securing the cable shield bond 2 to the tongue 98. The member 15 can be unscrewed and the frame 8 pivoted after release of the lock member 35 to release the cable shield bond 2 from between the legs 9 and 10. The apparatus 1 is then removed from the cable 4. It is to be understood that a similar cable shield bond is secured to the cable shield of the other cable (not shown) of the splice and that a conductor 106 electrically connects the cable shield bonds.  
  lt is to be understood that while I have illustrated and described certain forms of my invention, it is not to be limited to the specific form or arrangement of parts herein described and shown.
