PROBLEM TO BE SOLVED: To provide a pipe joint which can surely prevent the leakage of fluid even if rubbish and garbage adhere on a plug tip, is easy in the operation of an outer cylinder body, and can be reduced in diameter when achieving a compact size by diameter reduction while simplifying a seal member.SOLUTION: This pipe joint comprises a plug 1 and a socket 4. The plug 1 has a groove part 11. The socket 4 has: a main cylinder body 5 formed with a penetration hole 52; an inner cylinder body 6 arranged at an internal peripheral side of the main cylinder body 5; an outer cylinder body 7 arranged at an external peripheral side of the main cylinder body 5; and a lock member 8 arranged in the penetration hole 52. In the pipe joint, there is formed a seal part which performs secondary seal in two points between an internal peripheral face of a tip side rather than the penetration hole 52 in the main cylinder body 5 and an external peripheral face of the plug 1, and between the lock member 8 and an internal peripheral end of the penetration hole 52 in a state that the plug 1 and the socket 4 are connected to each other. |
