The invention relates to a sealing arrangement with an elastic sealing ring, which is located in sealing fashion between a first and a second component in a continuous groove (3) running around the first component, and is compressed in the groove in installed state, deforming its cross-section. At least one supporting ring (21, 22) is provided, which lies in sealing fashion against the sealing ring, while an opposite, supporting surface (9) lies against a groove flank (6) The supporting ring (21, 22) is positioned by the compressed sealing ring (2) in its position at the gap (13) to be sealed between the first and second components. As a result, extrusion of the sealing ring through the gap provided between the two components to be sealed is prevented.
