A security arrangement (1) against forcible entry is arranged on access-closing means, such as windows, window shutters, roller shutters and/or doors of buildings, or lids, doors and/or drawers of cabinet-like elements having at least one openable and closable part (7) and a frame (4). This arrangement (1) consists of a bolt holder (3) secured to the frame (4) and provided with a bolt which may be brought to a locked and to an unlocked position, as well as a bolt receiving part (8) secured to part (7) which cooperates with the bolt receiving part (3). When part (7) is pushed, the bolt receiving part (8) may be moved in relation to the bolt holder over a predetermined distance (a) at least in the opening direction of part (7) between end positions. The end positions of the distance (a) are monitored by surveillance means. When the end positions are reached, the surveillance means emit a signal which actuates an alarm installation (42). |
