The U-shaped element partially encircles the shank of a door knob assembly and the two arm portions fit into the two arm receiving apertures to lock the door. A device for keeping the U-shaped element in a locked position is built into the U-shaped element. A preferred embodiment utilizes a notch on the U-shaped element to keep the device in a locked position.
