Claim 0:
1. 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 first inner contour has a chamfer in the region of the first circular segment,
an inside diameter of which chamfer decreases in the axial direction of the assembly group starting from the side opposite the pressing area.
