A selection unit (15) is movable between two positions to selectively permit the taking up of a rotating pin (14) and the driving unit. A control unit (16) controls the movement of selection unit between the two positions. The rotating pin is driven in rotation by a maneuvering key exterior to the system. The selection unit is movable between one position in which the rotating pin is free in rotation with respect to the driving unit, and another position in which the pin and the driving unit are integrated in rotation.</p> |
