In the pipe joint device to be formed, while forming each internal flow path on the introduction side and the discharge side divided by a partition wall,
Each internal flow path is opened to the outer peripheral portion by each of the communication ports on the introduction side and the discharge side, and a pipe joint body having an opening / closing valve equivalent part for opening and closing the flow path is provided between each communication port, and a pipe joint body. On the side corresponding to the connection end, a restraining mechanism provided with restraining means for engaging and restraining the male joint member to be plugged in is provided,
In the internal flow path on the side corresponding to the connection end, a joint mechanism section having a female joint member that is slidably fitted and constantly pressed to the connection end side is provided. Provided with a release member having a communication channel which is slidably inserted therein, is constantly resiliently pressed to the connection end side, and is capable of opening and closing an opening / closing valve-equivalent portion corresponding to each of the introduction ports and the exit ports. When the male joint member is not connected, the connecting means is maintained at the non-constrained position from the inner peripheral side by the female joint member and from the outer peripheral side by the release member. By closing the valve between the communication ports, at the time of connection, with the connection of the male joint member, the female joint member is shifted to the restraining position to allow engagement by the restraining means, and the release member is moved to the engaging position. In addition to maintaining the constrained state by shifting, the valve between the communication ports is opened by the communication channel. It is so arranged may release the restrained state by migrating the release member in the engaged position, the following effects can be obtained.
