Abstract
The invention relates to a coupling for a fluid line arrangement, said coupling being characterised in that a plane outer side () of at least one essentially D-shaped sealing ring () of a sealing unit is applied to a plane supporting layer () of a receiving section () of a coupling part (). In this way, in addition to a high twist rigidity of the sealing ring () in question, a very effective sealing action is achieved, even in the presence of comparatively weak radial pressure forces.
