Zusammenfassung:	A doubling-up fitting includes an expansion sleeve which has a sleeve base with a sleeve base opening and has at least one expansion tab which can be spread radially outward. An inner ring is axially displaceable in the expansion sleeve towards the sleeve base in a tightening direction in order to spread the at least one expansion tab radially outward. A threaded bolt with a screw thread and with a bolt head engages behind the inner ring in the tightening direction. A threaded part has a widened head and can be screwed to the screw thread of the threaded bolt. The opening diameter of the sleeve base opening and the clear opening diameter of the inner ring are each greater than the bolt diameter of the threaded bolt.
