<p>In the anti-burglary device for a movable closing part (6) provided for closing a building orifice or a housing orifice, especially for a swing leaf of a garage door, the closing part (6) is mechanically connected with pressure-force transmission to a coupling piece (3) which is displaceable for the movement of the closing part (6) and which can be displaced by means of an actuating device out of an initial position, in which the closing part (6) assumes its closed position, for the purpose of moving the closing part out of its closed position. According to the invention, the coupling piece (3) has a blocking element (1) and, in its initial position, engages by means of the blocking element (1), under a pressure force transmitted from the closing part (6) to the coupling piece (3) transversely to the direction of displacement of the latter, into a counterblocking element (2) with the effect of blocking against a displacement of the coupling piece (3) out of its initial position. <IMAGE></p> |
