A lock consists of an elongated track which is attached to the panel of a door. A slider runs in the track from a retracted position in which the slider is spaced apart from the knob which operates the deadbolt to an engaged position in which the slider is in contact with the knob and prevents it from turning. The slider can be locked in that position by means of a locking pin. The pin may also be used to immobilizes the slider in the retracted position.
