ABSTRACT:
A protective sleeve for a lock includes a circumferential wall delimiting a longitudinal through-hole. The circumferential wall includes at least one longitudinal slot, forming at least one shielding skirt for shielding a housing of a latch mechanism of a lock that extends into the protective sleeve via the longitudinal slot. A tab extends from a perimeter delimiting the longitudinal slot into the longitudinal through-hole of the protective sleeve. The tab is extended through by an associated mounting post of the lock. A lock with such a protective sleeve is also disclosed.
