ABSTRACT In order to produce butt joints between two thin-walled sheet-metal tube sections (22), a one-piece flanged ring (10) is used, which substantially comprises only a securing flange (12) protruding approximately radially outward, an arm (14) projecting from the inner end of the securing flange and a ring land (18) bent obliquely outward toward the securing flange (12) by the arm (14). The outer diameter of the ring land (18) is selected such that when it is driven into the end of the tube, it comes under pre-stressing and thus pro- duces a stable joint between the flanged ring (10) and the tube (22). The invention also encompasses a simple method for producing the flanged ring (10), in which an elongated, flat sheet-metal strip is first folded and then is bent into annular form, and further encompasses a butt joint, having two flanged rings (10) according to the invention, between two thin-walled sheet-metal tube sections (22). Finally, the invention also relates to a reliable fixation of the ends of the flanged ring against one another by means of a clamp (11) which can be mounted onto them. Fig. 2.
