ABSTRACT:
An electrical pin 230 has an elongate body which is receivable in a complementary socket of an existing electrical outlet, while two electrically conductive pins on the same plug are simultaneously receivable in respective sockets for establishing a power supply path for an electrical appliance. A resilient deformable ring 238 is held captive by the body of the pin 230. Two metal spheres 234 bearing respectively against an inner peripheral region of the ring 238 lie in a transverse passage 233 extending through the body of the pin 230. A screw 236 lying in a threaded passage 231 intersecting the transverse passage 233 bears against the spheres 234. In use the screw 236 urges the spheres radially outwardly, thereby expanding the ring 238 until it bears frictionally against an adjacent portion of an associated electrical socket. The pin 230 is preferably mounted in an insulating body (not shown) having a switch cover 38 projecting from the body in lateral relationship to the pin. In use the switch cover 38 denies unauthorized access to an electrical switch 39 located adjacent to the socket which receives the pin 230.
