A coupling arrangement for coupling lengths of hose together has a spigot element (16) that is substantially circular cylindrical and has a plurality of circumferentially spaced lugs (18). The element (16) is received in a socket member (14) which is slightly larger than the spigot element (16) for the spigot element (16) to be a snug fit therein. The socket member (14) has a plurality of apertures (20) that are circumferentially spaced and configured to receive the lugs (18). The spigot element (16) is of a resiliently deformable material so that it may be pushed into the socket member (14) with the lugs (18) clipping into the apertures (20). The lugs (20) are tapered to faciliate insertion, and the spigot element (16) has a peripheral bead (17) at its end to promote sealing. A hose system then comprises a number of lengths (12) of hose, each having a spigot element (16) at both ends and a number of tubular connectors (10), each having a socket member (14) at both ends. |
