ABSTRACT:
A stamped hardened sheet steel tapered ferrule with cantilevered radially resilient fingers is wedged by a spring against a tapered bore of a hardened steel housing. The fingers bend radially inwardly to grip a stranded steel cable in the ferrule bore in response to the spring action. When the cable is slid in the ferrule in one direction, the ferrule gripping the cable is further wedged against the tapered bore and further grips the cable. The cable is released when it is slid in the opposite direction pulling the engaged ferrule away from the tapered bore of the housing. The cable has a flag at one end which with the seal lock a hasp therebetween limiting the relative motion of the cable in the opposite ferrule release direction. In a second embodiment, the ferrule is in interference fit with a rod or cable and the spring is not used forcing the ferrule to always grip the rod or cable. The ferrule in both embodiments grips the softer cable with higher rotational force than the ferrule friction force with the housing bore so that rotation or twisting of the cable relative to the housing rotates the ferrule therewith. The cable can not be threaded out of the ferrule by rotating the cable. A lubricant or reduced friction material coating can be used to enhance relative rotation between the ferrule and housing.
