On the basis of a rod 4 suitably secured to each door to be locked, it consists of a ratchet (pawl) 1 mounted in a tiltable manner on a shaft 2 and which is provided with a deep groove 3 intended to receive the aforesaid rod 4, in such a manner that, when the rod 4 penetrates the groove 3, it forces the ratchet 1 into a tilting movement, at the end of which, if said ratchet is locked by a stop 6, it in turn acts as a means for locking the rod 4 and consequently for the door associated therewith. The stop 6 is embodied in the form of a pulley associated with a radial arm 8 of a ring gear 10 which, via a radial connecting rod 11 secured to the latter, receives the movement of an actuator arm 12 which, also in the manner of a connecting rod, is connected eccentrically to the stator of the actual electric motor actuating the doors, said stator being floating, in such a manner that, when the rotor is prevented from moving, because the doors are locked, it is the stator which rotates in order to provide the movement necessary to unlock the doors. In the usual case of two combined doors, a second ring gear 9 meshes with the ring gear 10 and simultaneously receives the movement for its actuator stop 6 on the ratchet 1 of the other door. <IMAGE>
