A heat-sealing joint in which a fusion-bonding portion in which a coil that generates heat is embedded is formed in a joint body, and a resin pipe can be inserted into the fusion-bonding portion. Along the axial direction from the end portion, a retaining portion having a plurality of split portions is extended, a diameter reducing member is provided on the outer peripheral portion of the retaining portion, and a resin pipe is inserted into the fusion-bonded portion, A heat fusion joint characterized in that the diameter reducing member is reduced in diameter by sliding the diameter reducing member from the base end side to the tip end side of the retaining portion to fix the outer peripheral surface of the resin pipe.
