PROBLEM TO BE SOLVED: To provide a hose connecting connector capable of preventing the seizure of a screw even if disassembling and assembling are frequently performed. SOLUTION: A nipple body 10 is integrated with a metallic nipple 12 integrally formed with an apparatus installing part and a hose insertion part and a resin sleeve 14 installed on an outer peripheral surface of its nipple 12. A screw 14e meshing with a box nut 30 is formed in a sleeve 14. A hose 40 is connected by reducing an elastic sleeve 20 in the inner diameter direction according to fastening by meshing between the nipple body 10 and the box nut 30. The screw 14e of the nipple body 10 (actually, the sleeve 14) is formed of resin, and the box nut 30 meshing with this screw part 14e is formed of metal. Thus, since the nipple body 10 and a member (a construction material) of the box nut 30 are made different even if the disassembling and the assembling are frequently performed, the seizure of the screw 14e is not caused.
