The binding is disposed substantially symmetrically about a plane of symmetry which passes through the insulator (1) and which is orthogonal to said conductor (5). It comprises a ring (10), two conductor-retaining branches (11, 6), and tightening means (21, 22) for tightening the binding. Each of said branches comprises a first end portion (8, 9) in the form of a preformed spiral retainer for wrapping around said conductor, an intermediate portion (6) in the form of an arc of a circle having a radius of curvature that is substantially equal to the radius of the bottom of said circumferential groove, and a second end portion providing an eye for engaging the tightening means. Both branches pass through the ring at the transition between their spiral end portions and their intermediate arcuate portions. At least one elastomer block (20) is inserted between said eyes to be held in position by said tightening means drawing said eyes towards each other.

Binding retaining an electrical conductor in a circumferential groove

A tool having two side rods spaced apart by a connecting crossbar facilitates clamping and unclamping a cable in a groove on an insulator cap. To clamp the cable, the crossbar is inserted into a first recess on the cap between the groove and a protruding stud, and the side rods are pressed against a front branch of a clamp wire pivotally mounted on the cap to snap the front branch into a second recess below a front guide surface on the stud. To unclamp the cable, hooked extensions of the side bars engage the front branch of the clamp wire and lift it out of the second recess when the crossbar is pressed against the front guide surface of the stud. Separate clamping and unclamping tools can be mounted on an insulating handle for pivoting between a rest position and an operating position and spring biassing means can be provided to urge each tool toward a rest position.
