In the form shown in Fig. 1, securing a structural tube 1, 2 to a bracket 10, a pair of jaws 12, 13 expand within the inner tube 2 to grip it and a pair of projecting arms 5, 6 which are expanded apart by a screw 9 to grip in a recess 10b in wall 10 by means of hooks 7, 8. The jaws 5, 6 have holes 23, 24 in which ramps 17, 18 act to tension them against the wall as the screw 9 is tightened. Teeth 22 on jaws grip the inner surface of the inner tube 2 of the structural unit. The jaws may be of metal or plastics. In a modification, Fig. 2, for securing rectangular structural members, the ramps 44, 45 of the outer clamping jaws are in front of the springs 52, 53, the screw 55 lying within these. The outer clamping jaws may extend beyond the tube (Fig. 3, not shown). The ramps may be at the rear end of the inner jaws, Fig. 4, and the outer jaws may be keyed to the tube, the springs being dispensed with. In addition (Fig. 5, not shown) the inner and outer clamping jaws may have interengaging teeth (139, 140) which assist the relative axial movement of these jaws. Alternatively (Fig. 6, not shown) this axial pressure is derived from toggle links (208, 210) between the inner and outer sets of jaws. In the form shown in Fig. 7, the outer jaws consist of springs 220, 221, axial pressure being derived from limbs 225, 226 engaging the turned-up ends 223a, 224a of the inner jaws.

[Also in Group XXXVI] A multi-phase circuit-breaker has current limiting fuses arranged in a removable housing and operatively connected with the tripper bar of the circuit-breaker so that the blowing of any fuse or the removal of the housing causes operation of the tripper bar to effect the opening of the circuit-breaker. The circuit-breaker construction is similar to that of Specification 783,366 without the bimetallic and electromagnetic tripping devices. In Fig. 5 a bar 64 is associated with the tripper bar 16 as shown and the bias of a spring 65 tending to move the bar to its tripping position is normally overcome by a spring 71 acting on a lever assembly 68 pivoted at 69 in the removable housing 50. On the blowing of a fuse 25, a striker pin 74 turns the lever assembly 68 to permit the movement of bar 64 under the bias of the spring 65 to trip the circuit-breaker. The movement of the bar 64 also occurs when the housing 50 with the lever assembly 68 is removed from the circuit-breaker. Specification 869,424 also is referred to.
