Device for blocking a door and method for its manufacture

Abstract

The device for blocking a door handle (22, 23) can be clamped under the door handle (22, 23). According to the invention, the device has a recess (16) for a key or a locking knob (21), which has a shape other than a circle to block the rotation of the key or locking knob (21). Thus, the door cannot be opened even with a key. When the device is supported against the adjacent door frame (32), the door handle (22, 23) is also blocked. Furthermore, a bolt (18) can be provided that is rotatable or slidable behind the door handle (22, 23), so that the device cannot be released even by vigorous shaking.
