PROBLEM TO BE SOLVED: To connect a duct hose to an exhaust hood easily and quickly by providing a duct hose connector having a fitting section fitting the socket of an exhaust hood and the end section screw port of the duct hose, and discontinuously forming screw threads on the inner face of the screw port. SOLUTION: This duct hose connector 1 is integrally provided with a fitting section 2 in an exhaust hood connected to the outdoors and the screw port 3 of a bellows-like duct hose, and screw threads 4 partially having discontinuous sections 5 are formed on the inner face of the screw port 3. A plurality of protruded streaks 6 extending in the axial direction are formed on the inner face of the fitting section 2. For the connection of the duct hose to the duct hose connector 1, the lower section of the end section of the duct hose is faced in the screw port 3 and is hooked on the outermost screw thread 4, then the upper section is faced in the screw port 3 while being pressed and is hooked on the outermost screw thread 4 to bite into the screw thread 4, and the subsequent screwing is reliably facilitated.
