ABSTRACT:
In a first embodiment of the invention there is a substantially annular and flat frame for circumscribing a latch, in a door or the like, by interfitting between the latching edge of the door and the door-way frame. The latch-circumscribing frame has a pair of blades formed thereon on the inner surfaces thereof, and a shank portion in which a sharp-pointed rod is threadedly engaged. An outermost end of the rod has a handle fixed thereon whereby with manipulation of the handle, the sharp point of the rod is forceably torqued into arresting engagement with the latch and, simultaneously, draws the blades into incisive engagement with the latch as well. Both the blades and the point of the rod tenaciously clasp the latch therebetween to prevent unauthorized unlatching of the latch. Accordingly, any standard door latch, or the like, can be effectively dead-bolted.
