PROBLEM TO BE SOLVED: To provide a pipe joint that provides a large holding force for a pipe member, thus preventing slippage from occurring at fixed portions, and provides a high dimensional accuracy and an assembly of high strength. SOLUTION: The pipe joint comprises: a core cylinder part 11 formed of two split joints 1 combined and into which a pipe member is inserted along a perpendicular direction; and a projecting cylinder part 12 formed to project from the core cylinder part 11. A bolt hole 13 is formed through the portion of the projecting cylinder part 12 near the core cylinder part 11. The split joints 1 are secured to the pipe member by a bolt and nut via the bolt hole 13. Protrusions 14 for biting into the pipe member are formed on the inner peripheral surface of the core cylinder part 11 in such a manner that two of the protrusions 14 are located within the same plane perpendicular to the axial direction of the pipe member, and that a line L1 connecting the two protrusions 14 deviates from the axis L of the pipe member.
