Abstract: The fitting is intended especially for forming the rear corners of a drawer and comprises at each end of the rear wall a hook formation extending therefrom in the plane of the rear wall. Each lateral wall's end portions is formed with an elongate opening through which the hook formation of the rear wall is entered. On the side remote from that from which the hook formation is entered through the opening, each lateral wall portion has an upstanding flange over which the claw or hook of the hook formation engages. On the opposite edge of the opening is a further upstanding flange towards which the other flange is slightly inclined to leave a gap less in width than the maximum thickness of the hook of a hook formation and at least one of the flanges is resilient so that when the hook seats over the edge of flange it is biassed to that position by the action of the flanges.
