ABSTRACT:
A casement lock for mounting on a cabinet part, especially without the use of a tool. A housing is adapted to be fixedly mounted in an opening of the cabinet part, and an operating shaft is rotatably mounted in the housing. A locking ring is disposed on an inner part of the housing to fasten the housing to the cabinet. The locking ring is axially displaceable on the housing part against the force of a spring supported on the housing. Projections on the housing axially engage in radially extending extensions of the cabinet opening. The locking ring has locking dogs that are offset relative to the housing projections and have inclined surfaces.
