Abstract: A split hinged sleeve circumscribingly engages a substantial length of stranded aluminum cable and includes a plurality of diametrically opposed wedges extending laterally from the sleeve. The sleeve is mounted within a frame having bearing surfaces contacting each of the wedges. On exerting a pulling force upon the frame, which force is resisted by the cable, the bearing surfaces act upon the respective wedges to force the sleeve to grip the cable and place the cable in tension.
