PROBLEM TO BE SOLVED: To securely connect a resin tube without using a specialized connection tool. SOLUTION: When a lock member 30 is slid to a lock position after the resin tube T is inserted into a joint body 10, a locking piece 20 is deformed in the radial inner side and a projection 21 is bitten into the outer periphery of the resin tube T to lock the resin tube T. Since the resin tube T is locked after inserted into the joint body 10, a frictional resistance when the resin tube T is inserted is reduced, and the tool is not required. Since the lock member 30 is formed to be slid along the outer periphery of the joint body 10 without bringing it into contact with the resin tube T, a sliding resistance is reduced, and the tool is not required.
