Abstract: The present invention relates to a connection in a pipeline. The connection comprises a first connecting portion (1a) of a first pipe (1), a second connecting portion (2a) of a second pipe (2) which is connectable to the first connecting portion (1a), a wearing region (A) which allows a certain mutual mobility between the connecting portions (1a, 2a) when they are in a connected state, a sealing region (B) which prevents leakage between the connecting portions (1a, 2a) when they are in a connected state and a centreline (11) which extends centrally through the connection. The wearing region (A) is at a radial distance (r A ) from the centreline (11) which differs from the radial distance (r B ) from the sealing region (B) to the centreline (11). The risk of the wearing region (A) coming into contact with, and causing damage to, the sealing region (B) on occasions when the pipes (1, 2) at the connection are being disassembled is thus eliminated.
