Abstract

A device for temporarily locking a door which has an extension arm having one end secured perpendicularly to a channel straddling an edge of the door and extending away from the channel and a retainer arm telescoped onto the retainer arm that can be oriented either vertically or horizontally for engagement with the wall so that the locking device can be positioned at any location on either the top or vertical unhinged edge of the door. A bar may also be attached to the retaining arm when the retaining arm is oriented in the horizontal position. The means for securing the device to the door is also provided with an adjustable spacer means for attachment to a door having one of a range of thicknesses.
