The invention relates to a press sleeve for a press fitting for producing a sealing non-detachable pipe connection, with a receiving portion (4) for receiving a fitting basic body (6) and with a press portion (8), wherein the inside diameter of the receiving portion (4) is adapted to the outside diameter of the fitting basic body (6) and wherein the inside diameter of the press portion (8) is designed to be smaller than the outside diameter of the fitting basic body (6) at least in certain sections. The press sleeve is distinguished by the fact that at least one retaining lug (10) which can be clamped resiliently inwards in the radial direction (R) is provided in the receiving portion (4) and that the retaining lug (10) has a free end portion (12) which, with the retaining lug (10) in the stress-relieved state, protrudes at least partially into the inner region of the receiving portion (4) in the radial direction (R).
