ABSTRACT:
An electrical plug safety device (10) disclosed comprises a clasp including an elongated pin (20) having an electrically nonconductive outer surface. A distal end (24) of the pin (20) is inserted through prong openings of an electrical plug in an open position whereupon movement of the pin to a closed position secures the plug against use. A connector (26) of the clasp has one end (28) that supports an attached end (22) of the pin and another end including a retainer (32) that receives the distal end of the pin in the closed position. An opening (34) of the retainer (32) is capable of receiving a lock shackle to thereby control use of the plug. The clasp is preferably made as a bent elongated metal wire (40) that has an electrical nonconductive outer cover (42).
