Abstract: A composite rigid rod for holding a door in closed position from inside a room by reaction with the room floor includes first and second telescopically connected metal tubes with the upper end of the uppermost rod being of Y-shape and being connected by a metal band to the door knob shaft which prevents the falling or other removal of the rod from the door knob shaft. Additionally, the metal tubes are adjustably connected to achieve a desired composite rod length and a retainer clamp is mounted on the inner surface of the door so that the rod can be swung about the axis of the knob shaft to position its lower end in the retainer clamp to hold the rod in an inoperative stored position.
