ABSTRACT:
An apparatus is provided for preventing the unauthorized use of an electrical device such as a power tool or television set. The apparatus has the further provision of being retained on an electrical cable associated with the electrical device. The apparatus has an enclosure having a bottom and a peripherally extending side wall with an open top portion affording an inner chamber. An aperture is included in the bottom of the enclosure for slidably receiving the cable with the cable extending longitudinally through the enclosure and thereafter the aperture such that the enclosure is retained on the cable between the plug and the electrical device. Spaced pairs of apertures are located at the top portion on opposite sides of the enclosure. The apparatus is slidably moved along the cable until the electrical plug is inserted into the chamber with the shackle of the lock then being inserted through the spaced pairs of apertures so as to limit the size of opening of the top portion of the enclosure when in the locked position to capture the electrical plug within the enclosure, thereby preventing unauthorized use.
