An espagnolette fastening arrangement is provided for an openable window or door member in which the ability to open or close the window is controlled by a slidable member 13 provided with fastening elements 14 which engage with a keeper element (16). Any attempt to move the window from the open to closed state with a locking element (15) already in the locked position results in the fastening elements (14) abutting against a stepped edge portion provided on the keeper element (16). This prevents further movement of the locking element (15) towards the fixed frame (11) and thus prevents undesirable impact of the fixed frame (11) against the locking element (15). |
