A stackable drawer box having a plurality of side walls and boxes for a coupling element disposed thereon. 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.

A stackable drawer box comprising: a plurality of side walls, and receiving means on at least two of said plurality of side walls for receipt of and retention of a coupling element which includes spaced parallel legs connected by a connecting portion and spaced parallel fingers extending substantially parallel to and from the spaced legs toward the connecting portion, said receiving means including lug members for inwardly biasing the legs and the fingers of the coupling element as the coupling element is forced past said lug members and a stop for engaging the connecting portion of the coupling element so as to enable a displacement in a downward direction of the coupling element located in said receiving means from an inoperative position, in which the coupling element is substantially located within said receiving means of a first drawer box, into a coupling position, in which the coupling element coacts with a second drawer box located subjacent to the first drawer box of two stacked drawer boxes so that said lug members of the second drawer box engage the fingers of the coupling element after the legs and fingers of the coupling element have moved past the lug members of the first drawer box, and a continued displacement in the downward direction of the coupling element relative to both boxes is blocked by said stop of the first drawer box engaging the connecting portion of the coupling element and said lug members of the second drawer box prevent displacement in a direction opposite to the downward direction of the coupling element.
