Abstract

When an insert member is inserted into a fluid passage of a fluid tube, the fluid tube is diametrically enlarged by a tapered section. When a female thread of a nut member is meshed with a male thread of a main body section, first and second edge sections are engaged so that they bite into the outer circumference of the fluid tube diametrally enlarged by the tapered section. Accordingly, various fluid tubes, which are identical in outer diameter size but which are slightly different in wall thickness, are reliably prevented from disengagement from a tube joint.
