ABSTRACT:
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.
