This disclosure relates to a coupling member for securing the butt ends of two panels to a central panel, and to the joint structure formed therewith. The coupling member is formed from first and second elongated members, the first elongated member having a tubular portion with internal and external threads, and an opposite end having a radial shoulder to abut the sides of a panel and an expanded head spaced therefrom. The second elongated member forming the coupling member has at one end a threaded stud to be received within the first elongated member tubular portion and at the other end a radial shoulder and an expanded head spaced therefrom. In the joint formed with the coupling member, the expanded heads engage flexible and resilient clips having slots to receive the ends of the coupling members and the clips are fixed within recesses in butt ends of two panels. The joints thus formed are flexible and hidden from view.
