ABSTRACT:
The invention provides a device for securing a window sash to the outer frame of the window so that, on the one hand the sash may be locked in a predetermined open position and on the other hand may be pivoted to open it fully. A single push-button serves both to disengage a catch in the predetermined open position and to release the sash for full opening.
