<p>The device comprises a support housing with an opening for the introduction of a hook connected to the door, a retaining member moving with respect to the housing between a rest position in which it enables the hook to be introduced into the opening and an operating position in which it is adapted to retain the hook introduced into this opening, a locking device including a locking member moving between a disengaged and an engaged position in which it is adapted to allow and respectively to prevent the retaining member from moving from the operating position to the rest position and a control device that can be electrically actuated and is adapted to control the position of the locking member. The control device comprises an electrically controlled actuator adapted, each time that it is actuated, to cause a toothed wheel having a predetermined cam or toothed control profile, which is coupled directly to a projection of the locking member, to move by a predetermined amount in such a way that in at least a first and respectively a second angular position of this wheel, this cam or toothed command profile retains and respectively releases the locking member preventing and respectively enabling it to move from the disengaged to the engaged position.</p> |
