Sleeve joint for pipes

A pipe fitting for producing a sleeve joint between two steel pipes, the pipe fitting having two longitudinal ends and, at each longitudinal end, a sleeve into which an insertion end of a steel pipe with an outwardly projecting projection extending at least in sections in the circumferential direction can be inserted,

• wherein each sleeve has on its end face a bar receiving space running around in the circumferential direction, as well as a sealing chamber for receiving a sealing ring, which is separated from the bar receiving space by a separating wall running around in the circumferential direction and also running around in the circumferential direction,
• wherein the bar receiving space is bounded on the end face by an inwardly projecting end wall which is interrupted in the circumferential direction in such a way that it has insertion openings for the insertion of bars, wherein the end wall has a bearing surface which extends at an acute angle of less than 45° to the radial direction and against which a mating bearing surface extending at the corresponding angle can bear against a respective bar, and
• wherein the sealing chamber, starting from the separating wall, initially tapers in the longitudinal direction of the pipe fitting and then widens again in order to accommodate a correspondingly shaped sealing ring, which has at one longitudinal end a radially outwardly extending retaining bead for abutment against the separating wall and at the other longitudinal end two sealing lips which are separated from one another in a fork-like manner and which enclose between them an intermediate space open at the end face.
