Abstract
A connector for 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 an internal cam that is rotated in place to drive radial pins outward to engage the inner surface of the tubing. Cam rotation is accomplished by screw means that are mounted transverse to the axis of the tube and engage the cam tangentially. In some embodiments, additional screw means engage the cam to cause contrary rotation to disassemble the connection.
