PROBLEM TO BE SOLVED: To normally stably secure a state to connect with a filler hose while enabling to be mounted on a fuel tank comprising a polyethylene outer face layer in an excellent way to melt by welding. SOLUTION: This connector is to connect the fuel tank T having the polyethylene outer face layer with the filler hose H and comprise a mounting part 1 comprising a protrusion for welding 10 made of polyethylene or blend polymer of polyethylene with synthetic resin having a gas barrier characteristic to be mounted on an opening Tb piercingly formed through the tank T on the outside of the tank T by heating/welding and a connecting cylinder part 2 to be engaged into a connecting end Ha of the hose H. At least outer circumference 20 of the cylinder part 2 is formed by synthetic resin hard to swell absorbing fuel more than polyethylene and high in dimension stability.
