PCT No. PCT/DE94/00452 Sec. 371 Date Oct. 26, 1995 Sec. 102(e) Date Oct. 26, 1995 PCT Filed Apr. 25, 1994 PCT Pub. No. WO94/25204 PCT Pub. Date Nov. 10, 1994The arrangement (100) has a retaining rod (10) that is divided into an upper part (18) that is capable of being attached to a lifting device and a lower part (1) that projects into a plugging rod (2), that comprises a rapid connection device for the firm gas-tight connection of the lower part (1) to the upper part (18) whereby this permits easy exchange of a worn plugging rod. The region of the lower part (1) of the retaining rod (10) that projects into the plugging rod (2) is provided with means for engagement (3, 4, 35) that, as a result of communal isostatic compression engage with the ceramic material of the plugging rod (2) and generate a gas-tight, non-detachable connection of the lower part (1) of the retaining rod (10) to the plugging rod (2).
