PROBLEM TO BE SOLVED: To provide a connector for a pressure-resistant and heat-resistant hose in which mounting operation and coming-off preventing operation to the pressure-resistant and heat-resistant hose can be simply executed without requiring extra force, and which has a small number of parts and a high coming-off preventing effect. SOLUTION: The connector comprises a joint body 1 in which a tubular insertion part 15 provided with a plurality of stepped parts 16 in a circumferential shape is protruded integrally and continuously to a cap nut 11 provided with a screw 12 on the outer peripheral face; and a fastening nut 2 which is externally fitted to the pressure-resistant and heat-resistant hose 3 beforehand and in which the screw 22 to be screwed to the screw 12 of the cap nut 16 is provided on the front side of the inner peripheral face, and a spiral protrusion 23 which presses the hose 3 by pinching it with the stepped part 16 of the insertion part 15 is provided on the rear side of the inner peripheral face.
