ABSTRACT:
An end cap for closing an open end of a pipe. The end cap is formed with a sleeve of plastics material closed at a first end by a wall and having tongues formed integrally with the sleeve on the opposite or second end. These tongues fit in openings in a plastics clamping ring at the second end of the sleeve and engage with a side of the ring to prevent removal of the clamping ring. The clamping ring holds a sealing ring of rubber material around the inside of the sleeve for sealing engagement with the pipe fitted into the sleeve through the second end of the latter.
