The lance holder for an oxygen lance has a substantially increased reliability and safety, since a valve disk slidable against the force of a valve disk spring by insertion of the lance is provided in a retaining body between the slag run back safety device and a gripping head. This valve disk is forced from the valve seat on insertion of the lance so that the refinery gas can pass through the lance holder without more. If through some error the lance is released, i.e. by slipping out from the holder, the valve disk automatically closes so that the oxygen gas provided can not flow through. A contact of the oxygen-supply hose with the lance holder attached to it is thus reliably prevented. At the same time the slag run back safety device and the clamping head are formed so that a very compact lance holder results.
