  • Lock and method of fastening same
    Patent number: 4727736
    Abstract: A lock possesses a lock housing which is connected with a cover plate protruding above the lock housing at all sides. Fastening clips which abut at the corresponding side walls of the lock housing and protrude beyond the rear or rear side thereof are arranged at at least two oppositely positioned sides of the lock housing. The lock is fastened to a flat object by inserting it into an opening through the flat object and bending over the fastening clips on the rear side of this flat object. A substantial simplification of the manufacture of the lock and its fastening in an opening of the flat object is possible due to this form of construction.
