<P>PROBLEM TO BE SOLVED: To cope with a problem that a gas appliance is not desired to be used as it is since a plug of a gas supply port of a gas appliance has a plurality of shapes, a plug to which a joint member is connected has a shape different from a plug to which a rubber pipe is directly connected and a reliable connection cannot be achieved when a plug for a joint member is erroneously connected directly to the rubber tube. <P>SOLUTION: A tip part 28a of an arm part 28 is situated in proximity to a tip of a plug 11 so that the connection of a rubber pipe at the tip part 28a is obstructed even when an attempt is made to directly connect the rubber pipe to the plug 11. When connecting a joint member, on the other hand, a tip of the joint member abuts on an inclined part 28b to be bent to expand the arm part 28 outside. The tip part 28a moves away from the tip of the plug 11 so that the joint member can be connected to the plug 11. <P>COPYRIGHT: (C)2010,JPO&INPIT |
