ABSTRACT:
A cover for the various locks that are often placed a few inches above the door-knob is provided. The cover is an elongated plate spaced from the door and having sidewalls extending almost to the door. The cover has a downwardly extending portion that surrounds the shaft of the door-knob and has a hole through the shaft of the door-knob and has a hole through which the door-knob passes when the cover is rotated on its hinges to an open position. A jamming device has an indent for receiving the key or handle of one of the locks on the door. The jamming device bears against the shaft of the door-knob and prevents the key or handle of the lock from turning. Hence, the lock remains locked when the jamming device is used.
