Abstract
Abstract The device has a first piece mounted on the frame and a second piece mounted on the leaf (or vice versa). The first piece contains two horns defining two rigid bearing surfaces with a groove in between. The second piece is formed by a base mounted on a leaf (or frame), a flexible arm integral with the base and a catch tenon or latch piece integral with the free end of the flexible arm. At closing, the arm lodges automatically in the groove. The first and second pieces are each composed of two parts of which the first is secured to the frame (or leaf), this first part containing a slide-way (or slide) whereas the second part which contains the locking mechanism has at its base a slide (or cooperating slideway) adapted to the slide-way (or slide) of the first part.
