A return stop selectively locks a rotatable inner ring to a stationary outer ring. A cage supports at least two roller pairs, each of which consists of two rollers, wherein a spring element spring-loads the two rollers against the outer ring. Each spring element is a double spring having two spring sections and a connecting section connecting the two spring sections to each other and to the cage. In response to rotation of the cage relative to the inner ring, one roller of each roller pair comes to bear against a ramp of the inner ring and the outer ring. The cage has a driver element at one end face which protrudes axially into the inner ring and can be connected to a contoured section on the inner ring in order to produce positive-locking attachment.
