PURPOSE: A water hose connection structure is provided to reduce processing steps and enhance productivity by connecting rigidly a heater pipe to a water hose. CONSTITUTION: In order to heat a vehicle inside, a water hose(10) is coupled at a heater hose(10), so that cooling water circulating a cooling system is supplied to a heater through the heater pipe(12). A variable chamber(22) having two hydraulic chamber(22a,22b) is provided to one side coupling terminal(20) of the water hose(10). Two hydraulic chambers(22a,22b) are filled by water or the other liquid. By inserting the heater pipe(12), the liquid of the hydraulic chamber(22a) is moved to the hydraulic chamber(22b). A fixing ring(26) is inserted to an outer edge of the coupling terminal(20), which the hydraulic chamber(22) is placed.
