A first element (12), is arranged on the side of a door panel (10) on which the hinges (26) are fitted, and a second element (13) which is arranged on the door frame (11). When the door is closed, the elements engage positively with one another, both vertically and at right angles to the plane of the frame. One element, which may be the first element, can be moved form inside the closed door, into a position in which the positive engagement is, or can be, lifted out. One of the elements may be a bolt, whose position may be adjusted longitudinally, and which may be locked in a position in which it is engaged with the other element. |
