Suspension device, in particular for curtains

To be able to insert a glider (2), not only at the end or at a notch of a rail (1), into the rail (1) and nevertheless ensure secure holding of the glider (2) in the rail (1), the glider (2) has very specific dimensions, along with a special shape. The T-shaped glider (2) measures, from each end (2011, 2021) of its horizontal flanges (201, 202) up to in each case a remote bearing surface (2042, 2041), situated thereunder, of a projection (204), more than the width (B) of the rail opening (101). The projection (204) is provided between the horizontal flanges (201, 202) and a sewn-on eye (203) which forms the vertical T-flange. The projection (204) is partly separated from the sewn-on eye (203) by a longitudinal groove (205), the groove base (2051) being at most the same distance away from the remote flange end (2021) as the width (B) of the rail opening (101). It is thus possible, with a multi-step movement causing opposite pivoting movements and different sliding movements, some individual and some combined, for the glider (2) to be inserted into the rail (1). In another operation, causing other movements in a manifold sequence and combination, the glider (2) can be removed again. Unintentional removal, however, is not possible. A drawing-in aid can make possible the joint introduction of a large number of gliders.
