A lock for a window includes a lock body mountable on the window frame having a base plate and a raised portion standing upwardly from the base plate. The raised portion is a hollow interior within which a lock handle projects and on which is mounted the lock handle for pivotal action about a pin transverse to the raised portion. The raised portion defines a substantially rectangular flat upper surface parallel to the base plate. The handle portion includes a flat plate acting as a cover for the rectangular upper surface together with a manually graspable arch shaped element projecting beyond the end of the plate portion. Within a recess underneath the arch shaped portion is provided a trigger latch engageable with a web across the hollow interior of the raised portion for latching the handle in a lowered lock position.
