ABSTRACT:
A sealing ring (10) includes an outer sealing region (11) with a sealing edge (18) which rests in the installed state against the surface region to be sealed, and a holder region (12) which is situated within the sealing region (11). To prevent or render the pulling out of the sealing ring (10) from the corresponding groove-shaped recess (13) more difficult, the groove-shaped recess (13) includes at least one offset holding shoulder (16), and the holding region of the sealing ring (10) includes at least one corresponding holding edge (17), which in the installed state of the sealing ring (10) holds the sealing ring shape-lockingly like a barb.
