摘要： PROBLEM TO BE SOLVED: To provide a flexible pipe joint for preventing a failure in inserting a pressing ring. SOLUTION: The flexible pipe joint 10 includes a joint body 20 and the pressing ring 24. The pressing ring 24 has a cylinder portion 76a, and an exposed portion 76b. Through the cylinder portion 76a, a flexible pipe 300 passes. The cylinder portion 76a is pushed through an insertion port 30 into the joint body 20. The exposed portion 76b is provided on the rear side of the cylinder portion 76a, and exposed to the outside of the joint body 20 even after the cylinder portion 76a is pushed into the joint body 20. The cylinder portion 76a of the pressing ring 24 has a to-be-fitted portion 77. The to-be-fitted portion 77 is inserted into the joint body 20 at its midway and held in the state that it is not completely inserted into the joint body 20. Onto the outer peripheral face of the to-be-fitted portion 77, a color is applied which is different at least from that onto each of the outer peripheral face of the joint body 20 and the outer peripheral face of the exposed portion 76b.
