Abstract (en)

The device (1) comprises: a support casing (2) with an opening (5) for the introduction of a hook member (A) connected to the door (P), a retaining member (6) movable between a rest position in which it allows the introduction of the hook member (A) into the opening (5) and a working position in which it is adapted to retain the hook member (A) introduced into this opening (5); a locking device including a locking member (9) movable between a disengaged position and an engaged position, in which it is adapted to allow and prevent, respectively, the passage of the retaining member (6) from the working position to the rest position, and control means (20 to 34) which are electrically activatable and are adapted to control the position of the locking member (9); and an electric switch (10) with an opposing contact (11) and a movable contact (13), the latter being carried by a first flexible conductive blade (14), mounted in the casing (2), the blade (14) being coupled to the locking member (9) in such a way that the blade causes the switch (10) to be closed when the movable locking member (9) is in the engaged position, in which it prevents the door (P) from being opened. The opposing contact (11) is movable between a position close to and a position remote from the movable contact (13), and the control devices (20 to 34) are also coupled to the opposing contact (11) and are adapted to control the position thereof in such a way that, when they cause the locking member (9) to pass from the engaged position to the disengaged position, they also cause the opposing contact (11) to pass from the position close to the movable contact (13) to the position remote from the latter, thus contributing to the opening of the switch (10).
