<p>A pipe joint in which a sleeve (15) integrally provided with a nut (14) is separated from the nut when the nut is screwed in and in which the timing of the separation is stabilized to secure sealing ability of a portion where the sleeve has cut into piping. The sleeve is integral with the nut before connection of piping (12). When the nut is screwed on to the joint body (13), a contact surface (15c) of the sleeve and a contact surface (13c) of the joint body (13) are in contact with each other, and as a result, the sleeve is cut off from the nut and separated. When the nut is further screwed on, a head section (15a) of the sleeve is deformed by being pressed by a guide surface (13d) formed on a joint body and the head section of the sleeve cut into the outer circumferential surface of the piping when a surface (15b) to be guided is guided by a guide surface.</p> |
