The arrangement (100) has a two-part securing rod (10) consisting of an upper part (18) which can be fitted on a lifting device and a lower part (1) projecting into a stopper rod which comprises a quick-release securing device for securing the upper (18) to the lower (1) part firmly and gastightly, facilitating the exchange of a worn stopper rod. The region of the lower part (1) of the securing rod (10) projecting into the stopper rod (2) is fitted with engagement means (3, 4, 35) which engage with the ceramic material of the stopper rod (2) by joint, isostatic pressing and produce a gastight, permanent joint between the lower part (1) of the securing rod (10) and the stopper rod (2). |
