To provide a pipe joint capable of easily and promptly connecting a male side connector and a female side connector without requiring a large work space and any tool.
This pipe joint is formed with a stopper 16 radially extending on a tip outer periphery of plural protrusions 15 protrusively provided at intervals along a circumferencial direction on an outer periphery of a male side connector 4 fitted with a tip outer periphery of a second pipe 2 so as not to come out therefrom. This pipe joint comprises a hole 21 in which the protrusion 15 and the stopper 16 are fitted on a flange 18 protrusively provided at a tip outer periphery of a female side connector 3 fitted with a tip outer periphery of a first pipe 1 so as not to come out; a axial stopper receiver 22 engaged with the stopper 16 when the protrusion 15 and the stopper 16 move to circumferencially one side within the hole 21, at circumferencially one side of a tip end part of the hole 21; and an elastic tongue piece 23 tilting so as to move down in a centripetal direction with approaching a base end side of the hole 21, on one side in a circumferencial direction of the hole 21.
