<p>The device comprises: a support structure (2) with an opening (3) into which, when the door (P) is being closed, a hook member (4) connected to the door (P) is introduced, a retaining slider (7), which is capable of partially- obstructing the opening (3) and retaining the hook member (4) and a safety mechanism including: a slide (30) translatable in the support structure (2) and having a first and a second control member (35, 36) cooperating with corresponding retaining formations (46, 45) of the support structure (2) and the retaining slider (7), respectively; such that when the door (P) is open, the control members (35, 36) engage with the retaining formations (46, 45) such that the retaining slider (7) is substantially locked with respect to the support structure (2); and when the door (P) is being closed, the hook member (4) causes a displacement of the control members (35, 36), causing the disengagement thereof from said retaining formations (46, 45), so that the retaining slider (7) is capable of translating with respect to the support structure (2).</p> |
