Piping structure

A piping structure for use in a vehicle having a female connector and a corresponding pipe to be connected with the female connector, both arranged to join each other while allowing no relative turning movements, comprising:

• the female connector of a tubular shape having a first connecting end portion thereof extending straight for connection to a resin tube and a second connecting end portion thereof extending straight for connection to the corresponding pipe;
• the resin tube fixedly inserted at one end to the first connecting end portion of the female connector and extending to the other end;
• the corresponding pipe having an insertion end thereof arranged for joining coaxially and turnably by snap fastening to the second connecting end portion of the female connector and extending along the axial direction;
• and
• a first bracket fixedly mounted to the periphery of the female connector for non-turning and a second bracket fixedly mounted to the corresponding pipe for non-turning, wherein
• when the insertion end of the corresponding pipe is inserted and connected with the second connecting end portion of the female connector, the first bracket and the second bracket turn about the axis of the second connecting end portion of the female connector relative to each other so that connecting portion of the first bracket and connecting portion of the second bracket are coincided and coupled with each other.
