Abstract

A hinged cover encloses a projecting portion of a deadbolt lock, the projecting portion having a keyhole therein. The cover includes two shells, each having an inwardly directed flange thereon. By means of a retainer unit provided with a groove, the flanges are received in the groove to prevent removal of the cover when an auxillary lock is employed to keep the cover in its mated relationship so as to conceal the projecting portion of the deadbolt lock and the keyhole contained therein.
