Abstract
A locking device for a pivoting window includes a link which is completely embeddable inside the body of the lock mounted on a frame and a strap affixed to the window, the link being set in motion by a combination of sliding and pivoting movements transmitted from the translation motion of an operating knob, parallel to the body of the lock and obtained with pawns attached to the link evolving inside knob-holes of the strap and the body of the lock. This low-crowding device enables locking of the window with constant compression of the watertightness joint of the window.
