<p>A door locking device includes a housing having a lateral hole and a stop rotatably engaged in the lateral hole. A chain has one end secured to a door panel and has a head secured to the other end for engaging in the slot. A latch is extendible inward of the lateral hole for engaging with the stop. The head is movable over the stop into the slot when the latch is engaged with the stop and is prevented from moving over the stop by the latch so as to be prevented from disengaging from the slot. The door panel may be opened for a small gap only when the users are not home.</p> |
