The displacememt of the bolt (8) is achieved via a mano &cir& euvring device in the form of a lock (14) which is arranged to lock said device. The mano &cir& euvring device is mano &cir& euvred via a key to the lock (14), which key can be inserted through a recess (7) in the door-frame or window-frame (2) in order to mano &cir& euvre the device, which in itself is a lock. The device also comprises a driving device (9) which is arranged co-axially around an engaging element (30) and in a reciprocally rigid connection with the lock (14).
