Abstract
An element, such as an electrode, to be clamped by a clamping device passes slidingly through the interior of a rigid tube, a portion of which is disposed in a fluid chamber defined within a body of the clamping device. A flexible tube, for example made of nitrile rubber, surrounds said portion of the rigid tube and the latter has a part thereof cut away to expose the electrode to the flexible tube. Fluid in the chamber can be pressurized to a relatively high level in order to press the flexible tube against the electrode and thereby clamp the latter firmly, or to a relatively low level in order to retain the electrode frictionally while allowing it to move through the rigid tube.
