Abstract

The device comprises:
  • a support structure (2) in which is defined an aperture (3) for the introduction in a predetermined direction of a door catch (4) connected to a door;
  • a retainer member (10) movably mounted in the said structure (2) and having a seat (10) for receiving and retaining the door catch (4);
  • a conditioning mechanism (11-13, 18, 25, 33) cooperating with the retainer member (10) and operable to assume
    • a first condition in which it allows engagement of the door catch (4) with the retainer member (10) to retain the door in a closure position, and release of this coupling to allow opening of this door by application of a force on it; and
    • a second condition in which the retainer member (10) is maintained in a locked position in which it is able to retain the door in a locked closure position; and
  • a motorised control device (14-17) associated with the conditioning mechanism and electrically operable to cause passage of this mechanism from the first to the second condition and vice versa.
