Claim 14:
15. In combination an acoustic panel having a front surface and a rear surface and an impaling clip configured for mounting said acoustic panel on a support structure, said impaling clip comprising:
a base in a form of a planar member including a planar undersurface configured to be disposed on an outer surface of the support structure, said base including at least one planar window contiguous with said planar undersurface, said at least one planar window being of a four-sided polygon shape having a pair of opposed side edges extending vertically parallel to each other, a top edge and a bottom edge, said top edge and said bottom edge extending horizontally parallel to each other; and
at least one prong having a longitudinal axis, said at least one prong projecting outward perpendicularly from said at least one planar window at said bottom edge and directed towards said rear surface of said acoustic panel, said at least one prong being configured to be directed away from the outer surface of the support structure and comprising a leg portion, a sharp head portion having a free end in a form of sharp main point, and at least one subsidiary point, said sharp main point being disposed on said longitudinal axis, said longitudinal axis extending perpendicularly from said bottom edge, said at least one subsidiary point being in a form of an undercut barb having an edge extending at an acute angle with respect to a side edge of said leg portion, said sharp main point being configured for penetration of the rear surface of the panel, whereupon said sharp head portion, said at least one subsidiary point and at least a portion of said leg portion enters and is fixedly held within the material of the panel between the rear surface and the front surface thereof, with said at least one subsidiary point resisting extraction of said at least one prong from within the material of the panel.
