A removable L-shaped clip fastener of integral, one-piece construction, that is inserted between the risers of installed metal structural roof panels for use in attaching and supporting insulated ceilings, light fixtures, paddle fans, simulated beams. The clip fastener has a long leg and a short leg normal thereto. The long leg has and arcuate and edge-sharpened distal portion to facilitate insertion of the long leg between the risers; the long leg has bent-back ears defining limit stops to limit the extent of insertion of the long leg between the risers; the long leg has a longitudinal axis; and the long leg has a twisted portion at an angle of approximately 22.5 degrees in a radial direction relative to the longitudinal axis of the long leg, and such twisted portion wedges against the inside surfaces of the risers to render the clip fastener self-tightened and self-locked.
