A tang extends from a cover pivotally attached to a mounting plate of an electrical outlet to interconnect with and lockingly engage a lip extending from the mounting plate. A key, insertable through a keyway in the bottom side of the cover, is used to force the tang upwardly out of engagement with the lip and to unlock the cover from the mounting plate. Subsequent downward pivotal movement of the cover toward the mounting plate will relock the cover.
