The upper portion of a panel can be slidably suspended in an elongated guide rail at the underside of an elongated support by connecting the upper portion of the panel with two spaced-apart carriers each of which is provided with an upwardly extending follower including one or more pairs of rollers extending into the interior of the rail from below. The carriers can be separably attached to and are then turnable in bearings which are recessed into the upper portion of the panel, or each carrier can be provided with an anchoring device having one or more knives which penetrate into the material of the panel when a main portion of a carrier is received in a recess of the panel and the anchoring device is thereupon turned relative to its carrier. The overhead support can be provided with clips which releasably hold the panel in either of two end positions and/or with stops which can arrest the panel in a preselected end position relative to the guide rail.
