Abstract
Abstract A clip for securing a detachable electrical plug and cable assembly in an electrical receptacle having a hinged cover plate. The clip has first and second body members; means for securement of the first body member to the electrical plug and cable assembly; means for rotatably attaching the second body member relative the first body member; and biasing means integral with the first or second body members for pressing an adapted end of the second body member against the outside suface of the cover plate and bias the cover towards a closed position such that at least a portion of the inside surface of the cover plate presses against the plug to secure the electrical plug and cable assembly against relative movement with the receptacle. The first and second body members of the clip are preferably made from metallic wire or plate, but may be made from polymeric materials or combinations of polymeric and metallic materials. The clip is particularly useful in securing an electrical plug and cable assembly against relative movement with electrical receptacles used in Vehicle Tractor-Trailer applications.
