A portable locking system for hinged door improves on the type having a right-angle end of a first member for engaging a strike plate in a door frame and second member with a right angle end for pressing against the door and laterally and detachably engaging the first member. The detachable lateral engagement of this invention includes a series of holes tangential to each other in the first member and a plurality of juxtaposed pins protruding from the second member in position for adjustably engaging any corresponding selected holes in the first member. The system preferably includes a "U"-shaped keeper for holding the first and second members together for carrying them, or after installation. For identification in the dark and for ease in handling, a second angled-end of the hole plate is made longer than the first end. Similarly, one of the legs of the "U"-shaped keeper is made longer than the other.
