摘要： An attachment for an electrical outlet box, junction box, or similar receptacle is swiftly, manually engageable in an opening of the outlet box. The attachment is inexpensively formed, preferably of a thermoplastic material, and is of a design lending itself to manufacture by the extrusion process to further reduce the cost of making it. The attachment may be of single or double form, and typically includes a resiliently flexible clamping leg one end of which is integrally formed with a mounting means readily engageable in the mounting opening of the outlet box. The other end is integral with a clamping head, that at least partially overlies a cable entrance, and is formed with serrations that bite into the surface of non-metallic, sheathed cable. When a cable is inserted it deflects the clamping head and leg against the spring tension of the leg. A force now exerted on the cable tending to pull it out of the outlet box causes the clamping head to grip the cable and at the same time, a force is transmitted through the leg tending to bind the mounting means against the adjacent wall of the outlet box. In this way the cable is securely locked in place. Intentional removal is readily permitted, through provision of means on the clamping head adapted to receive the bit of a screwdriver or the like, allowing force to be exerted against the head and leg tending to disengage the same from the cable.
