The deflecting members consist of flexurally elastic material, for example a spring-steel strip. The guide channel consists of a metal profile (1), for example made of brass, in which two edge flanges (6, 7), which are bent in a C-shaped manner and the open sides of which are directed towards one another, laterally adjoin in one piece a plane web part (5). The guide channel forms a right-angled piece consisting of two legs (2, 3) which are connected to one another by means of a curved middle region (4). So that the deflecting members can run with slight lateral play and without the risk of jamming in the metal profile (1) serving as a guide channel, the metal profile (1) is provided, in each of the two transitional regions between the web part (5) and the edge flanges (6, 7), with a bead (8, 9) extending longitudinally and projecting into the clear profile cross-section. <IMAGE>
