A lance holder 1 characterized by a high level of operating safety is equipped with a holder or tube fixing system which reliably prevents even a bent lance tube 2 from turning in the lance holder 1. The clamping head 3 has a fixing part 4 and a clamping part 5 which ensure punctiform fixing by means of suitably- displaceable pressure elements 16 in the form of balls 20. Three such balls 20, 20' are distributed around the circumference and provide for secure fixing and a wide tolerance range in respect of the dimensions of the lance tubes 2. Said wide tolerance range is also ensured by the possibility of using sealing sleeves 6 with a large internal diameter, which are pressed securely and directly against the wall 18 of the lance tube 2 without compression by insertion of a wedge 22.
