Abstract: An annular gasket for an electrical connection of the kind comprising a socket-outlet casing (6) and a plug casing (7), said gasket extending in an axial direction (X) and comprising a cylindrical base (2) surmounted by a skirt (3) extending axially from the base (2), the skirt (3) presenting an inner wall (3b), an outer wall (3a), and a rounded free edge (4), each of the inner wall (3b) and of the outer wall (3a) presenting, a continuously curved shape in radial section view, the thickness of the skirt (3) decreasing in continuous and non-linear manner from the base (2) towards the free edge (4), the skirt (3) presenting a concavity oriented towards the inside of the gasket, whereby the skirt (3) folds over onto itself when axial stress is exerted on the free edge (4).

Abstract: A socket-outlet (10) that extends along an axial direction (X) and that includes at least one housing (18c) that is configured to receive a pin (94) of a plug (90), and a safety disk (12) that is movable in turning between a protection position that prevents access to said housing (18c) and a connection position that allows access to said housing (18c). The socket-outlet (10) includes a turning device (12c1, 14, 14a) for turning the safety disk (12), which turning device is configured to co-operate with the plug (90), the turning device bringing the safety disk (12) from the protection position to the connection position during relative axial movement between the socket-outlet (10) and the plug (90) while the plug (90) is engaging in the socket-outlet (10).
