ABSTRACT:
A safety cover for an electrical receptacle has a receiving plate fitting over an electrical receptacle, and a cover assembly having a cover edge extending around the periphery thereof hinged to the receiving plate to pivot between a closed and an open position. The cover assembly has a plurality of locking projections spaced around the periphery of the cover assembly at positions so that they are incapable of simultaneous operation by a hand below a predetermined size. When the cover assembly is closed, locking hooks on the locking projections engage in locking hook apertures in the receiving plate structure and the cover edge is snugly abutted against the receiving plate structure, and the cover assembly can be moved to the open position only by simultaneous deformation of the cover assembly at the positions of the locking hooks sufficient to move the locking hooks sufficientyl far inwardly to free said locking hooks from the locking hook receiving apertures.
