To form a connection between a straight (4) or curved (5) fitting and a water supply pipe, a flanges part of the fitting is clamped by a locking cap (1) against the shouldered end of the pipe (A or P). Projecting from the fitting (5) is a hooked lug (5') which engages teeth (2) or serrations on the outside of the cap, around its central opening, to give a locking action. In an alternative design, the fitting (4) has a tongue projecting from its surface to engage a groove inside the cap, to give a locking action. USE/ADVANTAGE - Particularly for plumbing applications. A good seal is maintained where vibration is present and the joint has remained dry over long periods of time.
