Abstract: A spacer for use between curved panes of a multiple-pane window in the door or in another part of a motor vehicle has an inverted U-shaped solid section and a straight hollow section with an internal space for a supply of desiccant and with one or more openings establishing communication between such space and the compartment which is surrounded by the frame and is flanked by the panes. The end portions of the solid section have studs which are sealingly received in sockets provided in the corresponding end portions of the hollow section. Portions of the solid section are bent to conform to the curvature of the panes. The cross-sectional outline of the hollow section can match that of the solid section.
