Claim:
1. A filling connector for filling a liquid container, the filling connector comprising: a liquid pipeline, for conveying liquid in a flow direction from a liquid inlet end portion having a liquid inlet opening to a liquid outlet end portion having a liquid outlet opening; and a gas pipeline, for conveying gas in an opposite flow direction while liquid is conveyed through the liquid pipeline, the opposite flow direction being from a gas inlet end portion having a gas inlet opening to a gas outlet end portion having a gas outlet opening, the liquid pipeline and the gas pipeline being formed integrally with one another; wherein the filling connector is formed as an injection-moulded part, with the gas pipeline being manufactured using injection technology; wherein the position of the gas outlet opening relative to the liquid inlet opening is visible from the outside during any pouring of a liquid in such a way that the liquid can be poured selectively past the gas outlet opening into the liquid pipeline; wherein at least one axial portion of the gas pipeline is enclosed by the liquid pipeline; and wherein the external cross-sectional area of the at least one axial portion of the gas pipeline enclosed by the liquid pipeline corresponds to at most 20% of the internal cross-sectional area of the liquid pipeline which can be flowed through.
