PIPE JOINT

PROBLEM TO BE SOLVED: To provide a pipe joint that can prevent the protrusion of a seal member caused by fluid pressure without preparing a separate part item even if diameters of pipes to be connected differ from each other, and by using a small number of part items.SOLUTION: A pipe joint is provided with a holding member 12 attached to a side of a seal member 2, opposite to a side of the seal member 2 on which a fluid pressure acts, in order to prevent protrusion of the seal member 2, the holding member 12 fixing fluid pipes 1, 1' to a joint body 10, the holding member 12 is constituted of arc-shaped divided bodies 12a to 12d that are formed being divided into a plurality of pieces in the circumferential direction of the holding member 12, and the divided bodies 12a to 12c are arranged along outer peripheries of the fluid pipes 1, 1' so that the respective divided bodies have clearances between the adjacent divided bodies 12a to 12d. Biasing members 13 for biasing the divided bodies 12a to 12d toward the outer peripheries of the fluid pipes 1, 1' are arranged between the respective divided bodies 12a to 12d and a socket 11.
