Abstract
A cover for restricting access to the female sockets of an electrical outlet, thereby protecting infants and small children and others of limited understanding against electrical shock. The cover includes a plate bearing externally threaded bosses which replaces the conventional outlet cover, safety caps of the push-and-twist type, and protective members which are clamped against the boss overlying the socket being protected by the safety cap to deny access to the socket, both when the socket is in use and when it is not in service.
