Abstract: A connecting mechanism for structural building system components for supporting radial, compression and tension loads by use of a captive, expanding/contracting jaw assembly which is caused to extended from an opening in the end of the connecting member into a connecting port located in the attaching component. The jaw assembly is then caused to expanded outward and to lock into the connecting port of the attaching component. Operation of the connecting mechanism is performed by causing an operating sleeve, which is located on the outside diameter of the connecting member, to be moved. This causes a structural bond to be made which firmly joins the connecting member and the attaching component. The procedure is reversed for simple removal of structural components or disassembly of the structure whenever desired.
