Abstract
Locking fitting for a door, window or the like including a sliding leaf provided with a front stile having the shape of a 'U'-shaped profile capable of fitting into a 'U'-shaped profile forming the corresponding stile of the sash-frame when in a closed position. The bottom of each of these 'U'-shaped profiles is capable of maintaining a distance between them so as to define a free space in which is positioned, at least one hook bolt integral with a movable actuating rod in a groove made in the 'U'-shaped profile of the sliding leaf, and at least one keeper fixed in the bottom of the 'U'-shaped profile of the sash-frame. The locking fitting includes at the actuating rod a mechanism to compensate, in the case of reduction of the cross-section of at least one of the 'U'-shaped profiles of the sliding leaf or the sash-frame, for the decrease in the distance separating the bottom of the 'U'-shaped profile corresponding to the sash-frame, in order to allow the introduction, into the free space of the at least one hook bolt and any cooperating keepers.
