Electrical connection element (1) provided with peripherally distributed electrical contacts designed to collaborate with the corresponding contact pins (5b) of a plug (2), a rotary safety disc (6) being provided and having peripheral perforations the number and position of which are chosen to, on the one hand, at rest, conceal the peripheral contacts of the connection element and, on the other hand, be superimposed therewith when the disc driven by the pins of the plug is rotated, whereas sealing blocks (9b) are positioned under the safety disc so as to seal off the peripheral perforations thereof in the rest position. The sealing blocks (9b) are positioned on a sealing disc (8) also provided with perforations, and which is formed under the safety disc (6) and mounted fixed in terms of rotation and able to move in terms of translation against the action of elastic means (10) which urge it towards the safety disc (6). |
