ABSTRACT:
An apparatus to prevent the accidental release of a wire rope used, for instance, as an underwater guy wire on a guyed tower. The apparatus has a clamp attached to the wire rope which, when the rope is released, hits a stopping ram which presses into wedge-shaped rope grippers. The wedges squeeze the rope and stop against wedge blocks which are attached to an inside portion of the guyed tower.
