ABSTRACT:
A universal connector is provided to secure an elongated member such as a cable, hose or pipe from relative movement of the member while allowing the member to pass completely through the universal connector. In accordance with the invention, a gripping element, having at least a pair of opposed star locking washers, is interposed between the interior surfaces of the connector and the member and surrounds the outside surface of the member to clamp the member in place upon compression of the star locking washers. The connector includes means to provide a compressive force on the gripping element to compress the star locking washers including a force transmitting ring arranged to bear upon one face of the gripping element as the ring is urged into the connector by the rotation of a knurled nut threadedly received on the connector.
