Abstract: Fluid coupling for connecting pressurised conduits. The coupling includes a spigot having a first circumferential groove disposed on an outer surface thereof and a socket having a second circumferential groove on an inner surface thereof. The spigot and the socket are adapted for axial engagement whereby the conduits are sealingly connected for fluid communication through the coupling and whereby the circumferential grooves are substantially in radial alignment. A releasable retaining member is moveable between a locked configuration, wherein the retaining member extends radially into both grooves to prevent axial disengagement of the spigot and the socket, and a release configuration wherein the retaining member is disposed substantially within one of the grooves and is substantially clear of the other to permit axial disengagement. The coupling further may include a release mechanism for moving the retaining member from the locked configuration to the release configuration.
