Abstract

The disclosure herein describes a safety guard which comprises a cover with openings adapted to be mounted over an electrical wall outlet and closure elements which are slideably mounted to the cover to expose or to cover the openings in registry with sockets of the wall outlet. The cover and the closure elements are structured so as to require two movements to displace the closure elements from a socket-covering position to a socket-exposing position. Also, a spring element connected between the cover and each closure element serves to bias the latter to the socket-covering position as the closure element is moved to expose the opening.
