Abstract
An arrangement for vacuum-tight sealing of electron tubes is provided with a vacuum pipe system which is connected to the electron tube by a tubularly-shaped connecting element. The connecting element is sealed in a vacuum-tight manner by a special thermal seal-off or melt-down unit after the electron tube has been evacuated. The thermal seal-off or melt-down unit is provided with a heating coil which is embraced by a component. The component is provided with an arresting element so that the component can be easily removed from the thermal seal-off or melt-down unit.
