Abstract

The device (1) comprises a support structure (2) with an opening (3) for the insertion of a hook (4) connected to a door (5), and a cam member (14) which is rotatable about a pin (13) translatable along an axis parallel to the direction of insertion of the hook (4), and which has a reaction profile (14a) disposed between a first recess or notch and a second recess or notch (14b, 14c). The cam member (14) is capable of:
  • adopting a rest position in which it is adjacent the opening (3) and its reaction profile (14a) bears against a stop member (25), and in which its first notch (14b) faces towards the opening (3) and can house an end portion (4a) of the hook (4) when the latter (4) is inserted in the opening (3), and
  • performing, as a result of a further insertion of the hook (4), a reversible rotational/translational movement towards a working position in which it is adjacent the stop member (25), which engages in its second notch (14c), and in which position the hook-like member (4) is held in the first notch (14b).
    • A toggle mechanism (16) is connected to the cam member (14), and can adopt a first configuration and a second configuration in which it tends to keep the cam member (14) in the rest position and in the working position, respectively.
