A filler pipe for a fuel tank of a motor vehicle includes at its cap end a cylindrical insert whereby an elastic sealing ring is arranged between an outer surface of the insert and an inner surface of the filler pipe made of plastic material. In order that a simple cost-favorable connection between the insert and the filler pipe is achieved combined with a good seal, the profiled sealing ring having an elongated cross-sectional shape is mounted on the insert under prestress. Furthermore, the insert and sealing ring are subjected to a common blow-molding operation.
