ABSTRACT:
A grip assembly is provided for locking an electric cord or cable to an electric appliance, such as a telephone receiver, electric drill, lamp base, or the like. The grip assembly in one embodiment comprises a threaded split bushing which is threaded into the appliance and which surrounds a molded sleeve on the electric cord or cable. The bore of the nut has a surface complementing the outer shape of the sleeve, thereby assuring that the cord will not pull out of the appliance and thus exert a strain on the electrical connections between the wires of the cord and the internal electric elements within the appliance. In a second embodiment the threaded split bushing is supported on the base of an appliance by a nut. The electric cord extends through the sleeve, and when the nut is tightened, the sleeve closes, as a vise, around the cord in a clamping engagement therewith.
