Abstract : Cylinder-to-cylinder attachment method and construction featuring nonutilization of mechanical fasteners or bonding, especially advantageous for attachment of cylinders which are composite or to be subjected to hydrostatic pressure. A fastening ring is interpositionally and rotatively engaged and aligned with a toothed axial end of each cylinder whereby the inwardly radial teeth for each cylinder appropriately mesh with the outer grooved circumferential surface of the fastening ring. The resultant joint is easily detachable and less susceptible than conventional joints to damage, breakage, degradation, stress concentrations and fluid infiltration.
