Abstract: A safety cover includes a one-piece body having an octagonal central section with two tabs extending outwardly therefrom. The tabs are offset from each other with respect to the central section top and bottom surfaces, and have a thickness that is essentially equal to one-half the thickness of the central section. Each of the tabs has a fastener-receiving hole defined therethrough, and adjacent tabs are coincident when one cover is adjacent to another cover. A fastener extends through the fastener-receiving holes and attaches one or both of the covers to a wall socket. Various fasteners can be used to ensure that unauthorized personnel will not be able to remove a cover from a wall socket once the cover is in place. The cover includes prongs that fit into the socket slots. One form of the cover includes a tearline between each tab and the body central section.
