ABSTRACT:
A connector for standard commercial square or rectangular tubing. The connector consists of a cubic or otherwise appropriately shaped block with projecting sections in each direction where tubing is intended to be connected. The projecting sections fit loosely inside the tubing. Each projection has internal cams that drive radial pins outward to engage the inner surface of the tubing. Cam movement is accomplished by a screw perpendicular to the axis of the tubing.
