The press fitting (10) for a pipe, in particular a plastic pipe or a pipe made of a plastic/metal composite material, is provided with a fitting element (12) which comprises a supporting element (16) onto which a pipe (20) to be connected can be pushed. Furthermore, the press fitting (10) comprises a compression sleeve (30) which has a holding end (34) on which the compression sleeve (30) is held on the fitting element (12). On its circumferential surface the compression sleeve (30) has a compression region (66) adjoining the holding end (34), in which region a pressing tool (62) acts on the compression sleeve (30) during the compression thereof. The compression sleeve (30) is provided at its holding end (34) with edge cutouts (36) which are open towards the end face (38) of the compression sleeve (30) and which each have a bounding edge section (40) situated opposite the end face (38) of the compression sleeve (30). A plastic ring (52) is situated on the outside of the compression sleeve (30) and is secured thereon against movements in the axial direction of the compression sleeve (30), wherein the plastic ring (52) has at least one axial projection (64) which extends right into the compression region (66) of the compression sleeve (30) and which can be destroyed when the pressing tool (62) acts on the compression sleeve (30) and/or is secured so that it can be separated from the plastic ring (52).
