The male joint member 230 is retained by being retained by the retaining inner peripheral surface 222 beyond the inclined cam surface 221. As a result, the male joint member 230 is retained at the valve opening position. That is, this state corresponds to the pipe joint body 2 shown in FIG.
00 is a valve-open state of the on-off valve device 210 in which the male joint member 230 is plugged in, and the primary side internal flow path A and the secondary side internal flow path B flow through the introduction opening 216. Maintained as possible. In this valve open state, the operation end of the external release member 220 stands by while protruding toward the connection end beyond the stopper ring 207.

In order to remove the plug-out from the pipe joint body, the pipe joint body 10 and the male joint member 70 are relatively differentiated from each other, and the differential state is maintained. Both the joint member 70 and the joint member 70 are actuated again in the pushing direction and, consequently, in the valve opening direction against the resilient pressure of the first and second ridges 48 and 57 (the withdrawal operation in the valve closing direction is naturally impossible as described above). This causes a relative differential between the two members once, thereby releasing the restraint of the external release member 61 and keeping the restraint released (unless the restraint is maintained). (Returning to the original restrained state), the external release member 61 is released again, and thus the plug-out removal operation of the male joint member 70 as intended can be performed.

Each of the retaining hard balls 29 engaged with the opening / closing valve side upper peripheral surface 76a and held in the constraining inner peripheral groove 67 of the external release member 61 is connected to the pipe joint body 10 and the male joint member 7.
With the relative differential with respect to 0 and maintaining the differential state,
First, the engagement with the open / close valve side upper peripheral surface 76a is released, and in the released state, the retaining outer peripheral groove 7
6 and 7 is placed in a floating state in which it can move toward the extra space portion 76b side, so that the plug-out is ready for disconnection (preparation for transition to non-connection) in FIGS. The operation of the external release member 61 which is abutted and held at the disengagement preparation position is enabled.
