In this arrangement, each of two elements, namely a support element and a flow control element forms on at least one of its two outsides part of a flow control surface. A joint element couples the flow control element movably to the support element and is arranged at a distance behind the flow control surfaces. The support element and the flow control element have in the area of the joint element, end faces that face each other. These define a space which is filled up by a soft and elastic filler piece.
