Abstract
A method and a device for connecting parts of an exhaust gas system which comprises at least one metal tube formed from a bellows and optionally further parts disposed coaxially within and/or outside of the bellows and at least one further system part to be connected to the metal tube, are characterized in that one end of a short connecting tube is inserted positively in an end of the metal tube and the other end is inserted positively in the system part to be connected to the metal tube, and the system part is moved to the end of the metal tube facing the system part, thereby leaving a gap, and the system part, the connecting tube and the metal tube being connected from the outside in one working step.
