This joint structure is provided by a pair of identical extruded plates, each being mounted to a furniture component part, and each having a pair of lengthwise extending tongues of a dovetail configuration separated by a complementary groove. One of the common sidewalls between the groove and an adjacent tongue is laterally offset to provide a relatively wide portion of the groove and a relatively narrow portion of the adjacent tongue intermediate the ends of the plates. The widened intermediate portion of the groove of one plate is adapted to receive an end portion of the complementary tongue of the other plate, and the narrowed intermediate portion of the tongue of the one plate is adapted to be received within an end portion of the groove of the other plate, when the plates are widthwise reversed and partially overlapped in length, to facilitate assembly of the parts.
