PURPOSE: A pipe joint device is provided to easily attach and detach a pipe inside a joint body according to mutual actuation between a spring ring and a bite ring section, and improve assemblability. CONSTITUTION: A pipe joint device includes a joint body and a pipe fixing assembly. The pipe fixing assembly includes a supporting ring(110), a packing ring(130), an expandable bite ring section(170), a contractible snap ring(190), and a spring ring(150). The supporting ring is fixed to the terminal portion of the dome expansion part. The packing ring is fixed to the supporting ring at the middle portion of the dome expansion part. The bite ring section on the front end portion of the dome expansion part grips the outer diameter of the pipe(P) to be disassembled. The snap ring fixed to the tip portion of the dome expansion part forward of bite ring section prevent the bite ring section from being separated. The spring ring between the packing ring and the bite ring section provides an elastic force for elastically moving the bite ring section between the front end and the middle portion of the dome expansion part. The dome expansion part includes an upwardly inclined portion, a horizontal expansion portion, and a downwardly inclined portion. The upwardly inclined portion is expanded and extended from the opening. The horizontal expansion portion is actually horizontal, and is extended from the upwardly inclined portion. The downwardly inclined portion on the terminal portion of the dome expansion part is contractibly extended from the horizontal expansion portion.
