ABSTRACT:
A thermosetting resin layer covers the outer peripheral surface of the nipple portion of a joint provided on one end of a connecting pipe. A hose having a reinforcing layer between a single- or double-layer inner tube and an outer tube is inserted over the nipple portion of the joint, and tightened by a caulked sleeve or clamp encircling the hose to form a joint structure. This joint structure provides a satisfactory seal for a long period of time, as its resin layer does not undergo any crystallization, but maintains elasticity.
