<p>A hose pipe coupling arrangement includes a socket (4) at one end of the pipe (3), wherein the socket (4) is dimensioned and shaped to receive an end portion of the hose (1) as a close fit therein and wherein the inner surface of the socket couples with the outer surface of the hose by means of a recess (5) in one surface accommodating a protuberance (2) of the other surface. The arrangement is such that, in use, pressure of fluid flowing through the hose (1) and socket (4) urges the protuberance (2) into the recess (5) so as to resist uncoupling of the hose (1) from the socket (4).</p> |
