PROBLEM TO BE SOLVED: To provide a bayonet pipe joint for fluid pipes with a simple structure, capable of not only connecting between fluid pipes by means of inserting the fluid pipes on a pipe supporting body, stopping, of course, fluid from leakage with a pressure in the fluid pipes, preventing backflow from leakage with an external pressure of the fluid pipe, preventing the fluid from leakage for the long time, but also improving reconnecting workability of the fluid pipes. SOLUTION: The bayonet pipe joint for fluid pipe is provides with a joint pipe body 10 having a pipe conduit in an axis center, a pipe supporting cylinder 20 set in the joint pipe body 10, a stopper ring 40 having a stopper tip engaged with the outer side of the fluid pipe inserted in the outside of the pipe supporting cylinder 20 and stored in the joint pipe body 10, and a cap nut 60 screwed to a front end of the joint pipe body 10, and not only at least a surface of the pipe supporting body 20 is formed of an elastic material but also a pipe stopping strip 21b is integrally formed on the outside of the pipe supporting cylinder 20 to secure to engagement with the fluid pipe 70.
