ABSTRACT:
A locking fitting for the sliding leaf of a window, door, or similar type closure which includes, in its housing, a slide connected to a bolt with a hook. The hook cooperates with a keeper which is fixed against movement with the fixed frame. After the movable closure is opened, the hooked bolt is maintained in its unlocked position by a blocking device having an elastic return. Further, the blocking device is formed by an assembly separate from the slide and includes a support which is clamped in the U-section of the movable closure. The support is fitted with a blocking lever which cooperates with the keeper when the movable closure is closed so as to free the hooked bolt for movement and, in consequence, the slide.
