Herraje con un gancho de retención que puede bloquearse mediante deslizamiento longitudinal

The invention relates to a fitting (14) that can be mounted on a leaf (12), to a window (10) and a door having the fitting (14), and to a method for mounting a fitting (14). The fitting (14) has at least one first arm (20) with a latch (24) and a pressing body. The pressing body can be moved relative to the latching part (24) in the direction of the longitudinal axis of the first arm (20) in order to cooperate with the first latching hook in an assembly position, so that the first latching hook cannot be offset inwards in the assembly position. Between the latching part (24) and the pressing body, an inclined surface is provided, by means of which the latching part (24) can be transferred from an assembled position into a released position. And in the loosening position, the first clamping and locking hook is not matched with the extrusion body any more, so that the first clamping and locking hook can deviate inwards. The fitting (14) can be easily assembled on and disassembled from the fan (12) in this way.
