ABSTRACT:
A gripper for locking against an elongated body such as a cable is subjected to relative displacement along the length of the body and is capable of locking at any place therealong, the gripper comprising a rigid member, at least two jaws provided with surfaces for locking against the body and a system for locking the jaws transversely on the body by wedge effect. Each jaw is associated with two substantially parallel bearing surfaces inclined relative to the elongated body, one surface being on the associated jaw, the other on the rigid member. A rolling member is interposed between the bearing surfaces for transmission of the locking force of the associated jaw to the rigid body and at least one shoe is associated with each pair of bearing surfaces. The shoe is provided with a surface for application against one of the bearing surfaces and an elastic assembly connects each shoe to the second bearing surface to maintain the rolling member between the second bearing surface and a rolling surface provided on the shoe.
