Abstract
A lock for a sliding window, the lock having a lock body, a pivoting handle attached to the lock body, the handle having a projection which extends into the lock body, an actuating lever fixed on the projection such that the actuating lever pivots with the handle, a separate lock tongue which extends from one edge of the window, and which is slidably moveable on the window in an up and down manner between a locked position where the lock tongue engages with a strike, and a free position, biasing means to bias the lock tongue into a naturally locked position, the actuating lever being operatively engageable to the lock tongue such that operation of the handle causes the lock tongue to move to the unlocked position against the bias of the biasing means.
