Abstract: A cover plate for an electrical duplex receptacle has an opening or openings therein as required to permit insertion of male plugs into the respective receiving receptacles. A female receptacle component projects outwardly from the cover plate and receives a stud projecting from the body of an inserted plug to thereby lock the plug against withdrawal that would otherwise occur if sufficient force is applied to pull the plug out of the receptacle and cause a loss of power to connected electrical equipment and resulting interruption in the operation thereof.

Abstract: An electrical cord locking connector joins electrical cords in series and presents a streamlined profile that minimizes interference in restricted spaces through which the cords must be fed to service a job site. The connector joins the ends of successive cords utilizing the outwardly projecting shoulder provided on the female socket of one cord in cooperation with a latch member on the male end of the connecting cord to lock the two cords together.

Abstract: An electrical cord locking connector joins electrical cords in series and presents a streamlined profile that minimizes interference in restricted spaces through which the cords must be fed to service a job site. The connector joins the ends of successive cords utilizing the outwardly projecting shoulder provided on the female socket of one cord in cooperation with a latch member on the male end of the connecting cord to lock the two cords together. A cord provided with a female end terminating in a replacement cord cap is provided with a socket presenting a generally circular face and an outwardly projecting shoulder at the face for engaging a releasable latch member of a mating plug, thereby preventing separation of the plug and socket under force until the latch member is disengaged.
