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 an enclosure having bottom and peripherally extending side walls and an open top portion affording an inner chamber. Spaced pairs of apertures are located at the top portion on opposite sides of the enclosure. An electrical plug and its associated cable are inserted into the chambe with the shackle of the lock then being inserted through the apertures so as to encircle the electrical cable when in the locked position to capture the electrical plug within the enclosure, thereby preventing unauthorized use.
