Abstract: A loss prevention guard for pockets which includes a flat, resilient, insert having a bowed central portion and a pair of substantially planar end portions. The hem of a pocket, adjacent the mouth of the pocket, is provided with a pair of spaced slots into which the ends of the insert are inserted, leaving the central bowed portion of the insert bowed inwardly into contact with the clothing to which the pocket is attached, i.e., the back of the pocket. The bowed central portion of the insert is preferably provided with an abrasive having a high friction contact with the article to be guarded, for example a wallet, to prevent the article from slipping by the insert.
