PROBLEM TO BE SOLVED: To enable mounting without erring the direction of a sealing material in which a part having fire resistance and a part having no fire resistance are integrally joined to each other in the axial direction, in a joint for a flexible tube. SOLUTION: A sealing material housing part 17 is formed in a cylindrical main body 11 into which the tip of a corrugated pipe 52 is to be inserted. In the housing part 17, an annular sealing material 20 can be mounted from the opening side of the cylindrical main body 11. The tip of the corrugated pipe 52 is inserted in the inner peripheral part of the sealing material 20 housed in the housing part 17. In the sealing material 20, a fire resistant part 21 to be placed on the inner side of the cylindrical main body 11 in the housing part 17, and a general rubber part 22 to be placed on the opening side of the cylindrical main body 11 and having no fire resistance are integrally formed. A mark 23 for distinguishing the fire resistant part 21 and the general rubber part 22 from each other is provided on the sealing material.
