1. An actuator for locking a latch of a motor vehicle door, capable of cooperating with a pin (1) for locking this door latch, which is capable of assuming in this actuator an unbolted position and a locked position (1a), comprising a rotary disc (2) wherein there is arranged an opening (3) for receiving the locking pin (1) and which is shaped so that with the pin bearing on an edge (3a) of the said opening, the rotation of the disc (2) in one direction (AR) entails the displacement of the pin from its unbolted position into its locked position and vice versa in the opposite direction of rotation (R) of the disc, characterized in that it comprises in combination : a) a first cam (C1 ) articulated for rotation on a second cam (C2 ) which is itself articulated on the disc (2), the first cam being positioned and shaped so as to bear on the locking pin (1) when the latter is in the locked position and to be capable of driving the second cam (C2 ) in rotation when the disc (2) is itself caused to rotate in a given direction from this locked position : b) and a hook (6) articulated on a casing (7) fixed to the disc (2), capable of cooperating with the second cam (C2 ) so as to be driven thereby in rotation when the disc (2) is itself caused to rotate by an electric command in the above mentioned given direction, until this hook (6) bolts the pin (1) in its locked position, the unbolting of the pin by the rotation of the disc in the reverse direction only being obtainable by a new reverse electric command.
