Abstract: An anti-theft guard for a wing window latch includes a hollow tubular sleeve and an anchoring element for releasably attaching the sleeve to the latch body. The sleeve is insertable at one open end over the latch body, and is of sufficient length to extend beyond the body and surround and shield a safety push button thereon from access except through an opposite open end of the sleeve. The sleeve has a longitudinal slot defined in a side portion extending from the one open end toward the opposite open but terminating short thereof. The slot has an outer portion located adjacent the one open end of the sleeve and an inner portion located remote therefrom and wider than the outer portion.
