An extrusion moulded member forming part of said first and second panel receiving means having a flange, in use, engaging around an edge of a panel and having a first groove, one edge of which is inwardly turned to constitute a lip. An extrusion moulded gripping member having a groove which receives said lip. One edge of said gripping member being arranged to abut against the inside of the first groove. A second edge of said gripping member remote from said first edge being arranged, in use, to engage the panel whereby the panel is resiliently gripped between said second edge and said flange, a second panel being retained by said second panel receiving means.
