Patent

CA 2414601

A device for fastening panels to tubular frames comprises a dowel element (10) and a sleeve element (11). An expander region (15) of the dowel element, comprising a plain cylindrical section (16) and a conically tapering section (17), is designed to react with a complementarily-tapering inner bore section (19) of the sleeve element when the dowel element is moved axially relative to the sleeve element to cause outward movement of an expandable section (20) of the sleeve element. The sleeve element has a flange (21) which acts as a depth stop and an undercut portion (22) so that a shoulder (23) of the expandable section lodges behind the hole in the tubular member when the fastener is set.
