ABSTRACT:
A safety device for shielding off the receptacles of an electric current tap or socket comprises a shutter member guided for sliding movement inside a body against the bias of a spring. The shutter member is disposed between tap holes in a forward cover intended for receiving pins of an electric plug and the tap receptacles. The shutter member is accommodated within the body in tilting support relationship with a back wall of said body which has two oppositely pitched surfaces set at a slight inclination angle which are adapted for blocking the shutter member against sliding movement when a portion thereof is thrust against one of the surfaces.
