<p>A pipe coupling comprises a body part having a hollow interior and a rotatable sleeve (2) captively mounted to the body part (1) of the coupling such that the end of a length of pipe (4) connected to the coupling passes through the rotatable sleeve to the hollow interior of the coupling. The rotatable sleeve has a tapered interior of narrowing diameter towards the pipe entry end of the rotatable sleeve. A circular band (5) is coaxially positioned inside the rotatable sleeve. In use a pipe end is pushed into the threaded sleeve to the hollow interior of the coupling, and through the circular band. Force on the pipe away from the coupling further closes the circular band about the pipe end. Preferably the circular band has a threaded interior. <MATH></p> |
