Abstract
The invention is directed to a quick connect/disconnect mechanism for fastening structural members together. The inventive apparatus includes flanges with nonfacing ringular surfaces on each structural member. A bolt or other mechanism aligns the structural members and prevents movement in shear of one with respect to the other. A resilient clip having end portions which are U-shaped in cross section and which extend around more than one-half the circumference of the flanges fits onto the flanges to hold and clamp the structural members together.
