Abstract: In the method of the invention, a portion of the metal tube is placed in a lumen of a metal sleeve (30) having a metal wall surrounding the lumen. The metal tube is placed in such a manner that an outer surface of the metal tube and an inner surface of the metal sleeve at least partially contact one another. The metal sleeve is affixed on the portion of the metal tube placed in its lumen for forming a metal tube, metal sleeve, composite system (10/30). The metal tube, metal sleeve, composite system (10/30), in turn, is placed in the passageway of the metal body in such a manner that an outer surface of the metal sleeve and an inner surface of the passageway at least partially contact one another, in order thereafter by plastically deforming at least the metal sleeve of the metal tube, metal sleeve, composite system placed in the passageway to form a force interlocking between the inner surface of the passageway and the outer surface of the metal sleeve. The so formed metal tube, metal sleeve, metal body composite system (10/30/20) can serve as a component of a measuring transducer, respectively a vibronic measuring device formed therewith.
