Claim 11:
12. An assembly group for a press fitting, comprising:
a substantially cylindrical pressing sleeve having a pressing area; and
a stop ring fixed to a first axial end of the pressing sleeve and delimiting the pressing area in an axial direction of the pressing sleeve, the stop ring comprising:
a first inner contour on a side opposite the pressing area for applying the assembly group to a fitting body of the press fitting;
a first circular segment and a second circular segment adjacent thereto and extending over a smaller portion of the first inner contour than the first circular segment;
a cross-section which is constant in a region of the first circular segment; and
an element arranged in a region of the second circular segment and projecting inwardly beyond the constant cross-section of the first circular segment so that, when the assembly group is applied to the fitting body, it causes a relative tilting of an axis of symmetry of the pressing sleeve with respect to a central axis of the fitting body,

wherein the stop ring has, on a side facing the pressing area, a second inner contour with projecting first areas and second areas receding with respect to the first areas for fixing the stop ring to the pressing sleeve.
