The device has a flagelliform flexible tine (1) arranged between an elongated rotating body (5) and a component that is rotatably connected with the body. The body cooperates with the component such that the tine is held at the body in a force fit manner. The component has an attachment, which lies against the body, and another attachment. A distance from the former attachment to the latter attachment is smaller than thickness of the tine in a region of the body. The latter attachment exhibits shape of a circle segment, and openings are arranged at ends of the segment.
