Abstract

A fastener for use with a sliding sash window. The fastener has a body (11) with a handle (14) mounted with the body for pivotal movement about a pivot axle (17). A latch tongue (18) is operatively coupled to the handle (14). A latch plate (21) has a latching surface (23) which is engageable in face to face contact with the end of the latch tongue (18). The latching surface (23) is spaced from the pivot axle (17) in the direction in which a sash (S) of a window is movable from a closed position relative to the frame (F) of the window. The handle (14) is movable about the pivot axle (17) to move the end of the latch tongue (18) away from its latching contact with the latching surface (23) of latch plate (21) to permit the window sash (S) to move from the closed position.
