Abstract

The press fitting for a tube, particularly for a plastic tube or a plastic/metal compound tube, comprises a fitting body (12) including a support shell (14) for mounting thereon one end of a tube (20) which is to be connected, a press shell (16) which is plastically deformable for pressing against the support shell (14) the end of a tube (20) to be connected that has been mounted on the support shell (14), an abutment element (30) arranged on the press shell (16) and having an abutment face (34) to be abutted by a pressing tool (26) for plastically deforming the press shell (16), and at least one press indication portion (40) projecting from the abutment face (34) of the abutment element (30) and extending externally on the press shell (16) into an acting region (38) within which the pressing tool (26) encloses the press shell (16) during deformation of the press shell (16), the press indication portion (40) being separable from the abutment element (30) by means of the pressing tool (26) during the deformation of the press shell (16). For axial fixation of the press shell (16) relative to the pressing tool (26) during the deformation of the press shell (16), the press indication p…
