PROBLEM TO BE SOLVED: To prevent generation of deterioration of sealability or insertion impossibility even when a corrugated tube to be inserted into a joint for a flexible tube is deformed oval. SOLUTION: This joint for a flexible tube 1 composed of a corrugated tube 2 is provided with a cylindrical main body 11, a push ring 25 of which tip part is driven into the cylindrical main body 11, and a retainer 44 disposed on the depth side of the push ring 25 inside the cylindrical main body 11. The flexible tube 1 comprises the corrugated tube 2 which can be inserted from an end part of the push ring 25 toward the push ring 25 and the inside of the cylindrical main body 11. The retainer 44 can be engaged with both the corrugated tube 2 inserted and the push ring 25. In an inner circumference of the push ring 25, a taper surface 56 for correcting the corrugated tube 2 inserted to be round is formed.
