Zusammenfassung:	An immersion device is provided for molten metal, as well as a method for making steel. The immersion device allows a trouble free operation. The immersion device includes a measuring head, a carrier for the measuring head, and a lance detachably connected to the carrier, preferably by a detachable tubular connecting element. A gas path runs from the lance to the detachable tubular connecting element. A gas tight connection is provided between a connecting surface of the lance and the detachable tubular connecting element. The tubular connecting element has wipers in the form of fins, which wipe the connecting surface of the lance during attaching and/or detaching the tubular connecting element and the lance.
