The present invention provides a sash lock for double hung windows. The sash lock is fabricated without a spring for biasing the cam into a closed or open position and further without a screw or fastening means to secure the lever, housing and cam together. The four primary components of the sash lock, specifically the lever, housing, cam and keeper mount may be fabricated from injection molded plastic as opposed to metallic materials.
