<p>PROBLEM TO BE SOLVED: To easily connect ends of connecting resin tubes to each other without water leakage. SOLUTION: Both ends of a fitting tubular body 2 of a larger aperture than an outside diameter of a connecting resin tube B are passed between ends of the connecting resin tubes B, B, and a clearance between the end of the fitting tubular body 2 and an outer peripheral surface of the connecting resin tube B is sealed by a ring packing 3 made of rubber installed on the end of the fitting tubular body 2. An outer periphery of the ring packing 3 is covered with split type fitting housings 1, 1, and these fitting housings 1, 1 are fastened with a bolt 11 and a nut 12. An inner peripheral surface of one end in the axial direction of the fitting housing 1 is engaged with an outer peripheral surface of the fitting tubular body 2 in a falling stop state, and biting teeth 20 provided on an inner peripheral surface of the other end in the axial direction of the fitting housing 1 are made to bite in on the outer peripheral surface of the connecting resin tube B.</p> |
