Claim:
1. A clutch for an automatic transmission in a motor vehicle, the clutch comprising: a clutch housing, the clutch housing forming a cylindrical internal space bounded by a cylinder inner circumferential surface; clutch plates received within the internal space; a ring groove that is open radially inward formed in the inner circumferential surface; recesses formed in the ring groove radially outside or an outer diameter of the ring groove; a retaining ring arranged in the ring groove, the retaining ring having an open circumference with two spaced ends; the ring groove and the retaining ring arranged concentrically at a central axis of the cylinder inner circumferential surface; one or more stops formed in the ring groove; and wherein a distance between the spaced ends and a distance from the spaced ends to the one or more stops are selected such that, in an assembled state, only one of the spaced ends of the retaining ring comes into contact with one of the one or more stops, while the other respective spaced end of the retaining ring is spaced from the one of the one or more stops, wherein the retaining ring is provided for axial support of an additional component of the clutch that exerts a circumferential force on the retaining ring during operation, the retaining ring thereby rotatable in the ring groove until a front one of the spaced ends of the retaining ring relative to a direction of the circumferential force makes contact with the one of the one or more stops, and wherein the spaced ends of the retaining ring bent radially outward and each extending radially into a respective one of the recesses, the one of the one or more stops for the front one of the spaced ends of the retaining ring is formed by the clutch housing at a transition from the ring groove to the recess.
