In FIG. 1 the numbers 2 and 4 denote round fixing plates having a hole 6 resp. 8 surrounded by a ring 10 resp. 12. Between the fixing plates a removable bar 14 is present, Cable 16 surrounds bone parts 17 (not fully shown). One end of cable 16 runs along the trajectory in which parts (a) to (f) are distinguished. Herein part (a) runs upward from below through the holes 8 and 6, then bends to the right in an outward direction and runs as part (b) along the upper surface 18 of the ring 10 to the outer edge thereof, where it bends downward to run as part (c) along the outer circumference 20 and 22 of the rings 10 and 12. The cable then bends to the left in an inward direction and runs as part (f) along the lower surface 24 of ring 12 to the inner edge of this ring, where it bends upward to run as part (d) through hole 8 in plate 4. Finally the cable runs as part (e) through the gap 26 in outward direction bringing end 28 out of the gap. The other end of cable 16 follows a similar trajectory but reversed with respect to center of the holes. The ends 28 and 30 can be grabbed and handled to be drawn and tension the cable 16 around bone parts to keep these fixed with respect to each other. Bar 14 prevents the cable from being clamped already and hampering the tensioning of cable 16. In FIG. 2. a top view of the embodiment of FIG. 1 is shown. Bar 14 can be seen through hole 6 in plate 2. In FIG. 3 bar 14 has been removed and the plates are pressed together by the cable surrounding the plates. The cable is secured from slipping back by the pressure exerted by the plates on the cable at (e), gap 26 being closed now. In FIG. 4 the same two plates in the same relative configuration as in FIG. 1 are present. In FIG. 4 the numbers of corresponding items have been raised by 400, so 402 is the same item as 2 in FIG. 1 etc. One end of cable 416 runs along the trajectory in which parts (a) to (g) ((f) excluded) can be distinguished. Herein part (a) runs upward from below through the holes 408 and 406, then bends to the right in an outward direction and runs as part (b) along the upper surface 418 of the ring 410 to the outer edge thereof, where it bends downward to run as part (c) along the outer circumference 420 of ring 410. The cable then bends to the left in an inward direction and runs as part (e) through the gap 426 until it reaches the part of the gap between the holes where it bends downward to run as part (d) through hole 408 in plate 404. Finally the cable runs as part (g) in outward direction underneath lower surface 424 of ring 404 bringing end 428 out of the gap. The other end of cable 416 follows a similar trajectory but reversed with respect to center of the holes. The ends 428 and 430 can be grabbed and handled to be drawn and tension the cable 416 around bone parts 417 to keep these fixed with respect to each other. Bar 14 prevents the cable from being clamped already and hampering the tensioning of cable 16. In FIG. 5 502 and 504 are two asymmetric fixing plates having holes 506 and 508 respectively The ring around each hole has a first part 510 resp. 512 the surface area of which is large enough to give sufficient clamping force on a cable following a trajectory as described before. In this FIG. 5 one end of the cable follows the trajectory described under FIG. 1. The part 532 resp. 534 of the rings at the opposite side of the hole with respect to the first part is smaller that the first part. A tensioning device 536 consists of a first part 538 in which a longitudinal bore is present provided with internal screw thread in which a hook 540 is mounted. The other end 530 of the cable has an eye 546 to which the hook 540 has been attached. The tensioning device 536 further consists of a second part that consists essentially of a recess 542 extending from about the center of the device to its end opposite of the side where the bore is present and extending over its full width. The recess ends at a wall 544. The thickness of this wall is such that it fits in the hole of the plates, leaving sufficient room for the cable to be guided through the holes along the clamping trajectory. Lower plate 504 forms part of the tensioning device. Plate 502 can move upward and downward with respect to plate 504. The bottom 544 of recess 542 is at the same level as the surface of plate 504. This allows ring 510 to be in contact over its complete surface area with ring part 512 of the lower plate when plate 502 is pressed downward when drawing on cable end 528 tensions the cable. Plate 502 is mounted on the tensioning device such that the wall 544 extends through hole 506. Turning hook 540 in a counter clockwise direction tensions the cable further. Further, also in this embodiment a bar can be inserted between the rings during the tensioning and then removed when the desired tension is applied. In FIG. 6 in hole 606 of top plate 602 the top of wall 644 sticking through said hole, is visible. Cable end 630 with eye 646 is connected to hook 640.
