The boxes and the coupling element are provided with lug members and stops enabling a displacement of the coupling element in a box from an inoperative position, in which a coupling element is present within a box of a single drawer box, into a coupling position, in which a coupling element coacts with the boxes of two stacked drawer boxes, and in which a displacement of the coupling element relative to both boxes is blocked by the lug members and the stops. A filing cabinet composed of a plurality of drawer boxes comprises a base and an upper portion, both being coupled to the drawer boxes in the same manner as the drawer boxes mutually.
