Abstract
A locking assembly for normally separable apertured structures which protect business fronts against burglary. The locking assembly includes a sturdy, straight pin which penetrates all apertures, and is part of a sturdy bracket which overlies a fixed standard or post. The arrangement is such as to permit a key operated locking device to lie flatly and directly upon the bracket so as to prevent removal of the bracket and its above mentioned pin. The overall arrangement is such as to guard against burglary by an unauthorized person using forceful tools, and to prevent access to the pin for the purpose of destroying or cutting it.
