The sash lock includes a rotatable lever having a tab extending therefrom and a spring slide deformable by rotation of the rotatable lever and movement of the tab against the spring slide for selectively causing a portion of the spring slide to enter and retract from the aperture to cause locking and unlocking of the first and second window sashes relative to each other. The spring slide includes a central aperture, the tab extending into the central aperture, rotation of the tab with the rotatable lever causing deformation of the spring slide and one of movement of the spring slide into or out of the keeper aperture. The housing has a shaft secured to the spring slide, the rotatable lever being rotatable about the shaft. The spring slide is preferably a spring steel slide. The apparatus may further include a member having member detents therein and secured to the shaft and rotatable member detents disposed on the rotatable member for entry into at least one selected member detent upon rotation of the rotatable member to one of an open or closed position.
