A tube joint includes a body made of a resin material and having a first end side with an edge. A connecting member inserted into the first end side of the body has an annular expanded section which outwardly projects from an outer circumferential surface of the connecting member and which engages with an inner circumferential wall surface of the body at the first end side. A ring member fitted to an outer circumferential wall surface of the first end side of the body presses the outer circumferential wall surface of the body radially inwardly. The ring member is positioned between the annular expanded section of the connecting member and the edge of the first end side, so that the body and the connecting member are prevented from disengagement.
