The locking bolt bar (5) is operated by a control rod (10) in the door frame and which in a closed position engages with a coupling element (11) on the control rod. The coupling element is in the form of a sleeve slid axially over the locking bolt bar, and possessing an axial groove (17) into which fits a bolt (16) protruding radially out of the control rod. The coupling element, in the sleeve connected to the door, is axially movable between two stops against a spring element (18). The control is axially movably positioned by an electromagnet or lever or cable, in a retainer joined to the door frame. |
