A pipe connector for connecting a static gas pipe P1 from a supply to a flexible pipe P2 to a gas consuming appliance comprises a first part 104 connected to pipe P1 and a second part 106 connected to pipe P2. The part 104 comprises a tubular housing 108 containing a valve member 118 automatically urged to its closed position by spring 142. A groove arrangement 163 is formed in tie exterior of extension 116. This arrangement comprises a continuous groove 167 around the extension, two lead-in grooves 165, and two diametrically opposed notches 169 in a side of groove 167. The part 106 comprises a tube 146 connected to pipe P2 and having a rotatable sleeve 152 carrying inwardly directed bayonet pins 160. The parts 104 and 106 are removably fitable together by inserting pins 160 along grooves 165 to groove 167 so that end 156 of pipe 146 inserted in extension 116 pushes back valve member 118 to open the valve and thus establish communication between pipes P1, P2. The parts 104, 106 are locked together by rotating the sleeve 152 in either direction to bring the pins 160 into the notches 169. <IMAGE>
