A ring member and ring members made of metal are tightened and installed to the outer circumferential surface of a body made of a resin material. Accordingly, the body is prevented from outward deformation. When a tube joint is used in a high temperature atmosphere, even if any force acts on a fluid tube in the direction to cause detachment from the tube joint due to any external force or the pressure fluid flowing through the inside of the tube joint, then the fluid tube and a connecting member inserted into the body are reliably prevented from disengagement.
