<p>The socket (700) has a cylindrical wall (400) for defining a slot, and a flap (600) for closing a section of the slot. The flap is movable in translation with respect to the wall, and includes two circular holes (604). A central upright (302) axially slides in a groove (203) to translate jointly with the flap. A filler plate (510) is mounted at one end of the central upright, and pivots between a close position of the holes and an open position of the holes. The filler plate freely pivots with respect to the central upright between the close and open positions.</p> |
