Method of forming a compression coupling between a fitting and a tube inserted into the retaining section of the fitting. The method involves use of a shaped part formed so that, during insertion of the tube into the fitting, the sealing ring set into an annular retaining groove of the fitting is not damaged by the sharp, outer edges at the front end surface of the tube. Before or during the insertion of the tube into the fitting, the sealing ring is elastically outwardly deformed from the inner contours by means of at least one installed shaped part. The tube end is then inserted up to a contact surface, which forms the interior boundary of the retaining section of the fitting. Thereupon, the parts are pressed together by cold deformation of the parts. The method and the shaped parts are installed preferably in sanitary engineering and are used wherever liquids or gaseous media are carried through tubes.
