Abstract
A lock adapted for attachment to a sash window/door without screws comprises: a shaft with a cam secured thereon is rotatably secured to a housing, with the cam disposed within a housing cavity and rotatable therefrom out of an opening, into an extended position. The housing may be a single integrally formed wall that preferably has a flat bottom surface. A first attachment leg protrudes out from the housing cavity to extend beyond the bottom surface, with a foot thereon extending beyond a first end of the housing. A second attachment leg protrudes out the housing cavity second end, with a foot thereon oriented toward the housing first end, and a locking tab extends from the housing bottom surface. Installation of the screwless sash lock is by receiving the first foot, second foot, and locking tab within correspondingly positioned openings in the window/door rail, through sequenced rotational and sliding motion.
