Hanging device and method of making same

A hanging device for mounting directly on a hollow member having at least one thin panel, said device comprising:

• a mounting member having a first surface for resting flush against an outer surface of said at least one panel of the hollow member;
• a first piercing means having a first leg projecting from said mounting member substantially perpendicular to said first surface thereof, and a second leg that extends at substantially right angles to said first leg in a direction away from said mounting member and essentially parallel to said first surface thereof, wherein a free end of said second leg has a sharp tip that is insertable in a self-piercing manner through said at least one panel of said hollow member;
• a second piercing means projecting from said mounting member substantially perpendicular to said first surface thereof and essentially parallel to said first leg of said first piercing means, wherein a free end of said second piercing means has a sharp tip that is insertable in a self-piercing manner through said at least one panel of said hollow member, and wherein said second piercing means and said first leg of said first piercing means are interconnected by a straight section that is disposed flushly against a side of a flat section of said mounting member that is remote from said first surface of said mounting member;
• and
• a separate hanging member for hanging and supporting objects, disposed on said mounting member on a side thereof remote from said first surface thereof, wherein said mounting member is provided with attachment means for cooperating and mating with attachment means of said hanging member, wherein said attachment means of said mounting member comprises flanges that project away from said side of said flat section of said mounting member that is remote from said first surface thereof, wherein said mating attachment means of said hanging member comprises a recess provided therein for receiving said flanges, wherein said flat section has sides that taper toward one another in a direction toward said first piercing means, and wherein said flanges join said flat section at said tapered sides thereof.
