Abstract: Shutter device for closing off the compartments of a power socket that has a live aperture and a neutral aperture in a front plate. The shutter device comprises a shutter piece that moves translationally between a rest position, in which the live and neutral apertures are closed, and an operational position in which they are not closed. The shutter piece comprises two arms positioned against the live and neutral apertures in the rest position and inclined at an angle to the direction of translation of the shutter piece.

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.
