Abstract: A releasable coupling assembly is provided for rib members or other members having a flat stock or bar-like configuration. The releasable coupling is provided for members which are at least partially overlapping one another, with the opposing mating surfaces of the members preferably being planar. One member carries a retaining clip defining a pocket for receiving the other rib member. Various embodiments are provided in which moveable or stationary pins extend into the pocket to engage the cooperating rib member to engage the rib member to prevent dislodgement from the overlapping condition.

Abstract: A stand for mounting a device having a rib member includes a mast, with a pair of spaced mounting clips secured to the mast. The mounting clips are spaced from the outer surface of the mast so as to form pockets therewith for receiving the rib member. Upon insertion between the mounting clips, the rib member is pivoted for entry into the pockets and a locking pin receivable in an aperture in the rib member prevents a dislocating pivoting in an opposite direction.
