Abstract: A pipe connection includes a connection body, a nut which can be screwed onto or into the latter and which has a conical bore which widens toward the connection body, and a pipe guided through a bore in the nut and having an outwardly projecting formation with two clamping faces. A first clamping face is parallel to the end face of the connection body and is supported on the connection body at least in certain regions when the pipe connection is in the clamped state, and the second clamping face is cone-shaped in a manner corresponding to the conical bore in the nut and is supported in the conical bore in the nut. The connection body has a radially encircling cutout by which a receiving space is formed for a sealing ring that is delimited by the first clamping face and has a polygonal, symmetrical cross section.
