A press fitted stud on one end of a metal strip is hooked into the opening of a striker plate in a door jamb and the strip extends in the space between the jamb and the edge of the door past the jamb and closed door. The extended end of the plate has holes for receiving a knurled locking pin which holds a locking plate tightly against the closed door and the door jamb to keep the door securely closed. Resilient pads of different thickness and compressibility on the locking plate facing the door keep the door tightly closed.
