Abstract: The invention relates to a pipe connection, consisting of a press fitting with at least one section which has a torus-like cross-section and which accommodates a sealing ring, an adjoining cylindrical section oriented towards the insertion end and/or such a section oriented away from the insertion end. The cylindrical section oriented away from the insertion end runs into an adjacent cylindrical section, forming a stop. The inner diameter of the latter cylindrical section is smaller than the other cylindrical sections. The pipe connection also consists of a conduit whose flat end area comes to rest on the inner stop of the press-fitting after being inserted into the same. A nondetachable, tight pipe connection is produced by closing a pressing tool with at least two pressing plates encompassing the press fitting. During the pressing process, the pressing plates act on the torus, including the sealing ring placed therein, and on the cylindrical section of the press fitting oriented towards or away from the insertion end. The invention is characterised in that an element (14, 21) which only allows the inserted conduit (4) to move backwards axially within a fixed limit is situated in the area of the cylindrical section (9, 25) oriented away from the insertion end, the inside clearance of said element when not under stress being smaller than the smallest possible outer diameter (18) of the inserted conduit (4) in terms of tolerance.
