A device for the automatic coupling of a teeming ladle to several gas pipes, comprising a first coupling part connected to a gas supply and a second coupling part attached to the teeming ladle, wherein several gas outlets are arranged in the first coupling part and several gas inlets are arranged in the second coupling part. Each individual gas outlet can be closed by a closing element in the first coupling part, wherein, when being coupled to the second coupling part, this closing element is pressed inwards into the first coupling part and releases the corresponding gas outlet. To bring about self-cleaning of the coupling parts before they are coupled together, the closing elements are designed in such a way that, when the two parts of the coupling are coupled together, before the sealing union of the two coupling parts, a single gas outlet is first of all released, before the other gas outlets are released.
