Jimmying of door locks by forcing the retraction of the door lock bolt is prevented or discouraged by a device which may be attached either to the door jamb or to the end wall of a door containing the door lock. The device has a first plate-like mounting member and a second plate-like member angularly connected to the first member, the second member being resiliently biasable towards the first member in response to contact with the other of the door member and the end wall upon which the first member is not mounted when the door is swung to a closed position. The device thereby blocks the clearance space between the door jamb and the end wall adjacent the bolt, preventing contact of a jimmying device with the bolt.
