Abstract
The disclosed invention is an apparatus for connecting two current conducting tubes, which also conduct fluids such as for example, a coolant. The connection apparatus conducts current from one tube to the other through a sleeve, the said tubes having a machined external surface against which the sleeve is pressed. A hose receiving hydraulic pressure is disposed between the sleeve and an external casing for providing a removable pressure against the sleeve for clamping the pipes in the sleeve. The present invention may be used in conjunction with a holder assembly for electrodes in an electrothermal smelting furnace.
