<p>A coupling (10) is provided between a sheet member (20) with an edge (22) of a thickness T, having at least one opening (24) formed adjacent the edge (22), and a receiving member (30) formed with a recess (32) of a width W and spacers (34) defining within the recess (32) a groove (36) of a width w, which meets the condition T <w <W. The recess comprises at least one projection (40) protruding into the groove (36), and the groove is adapted to slidingly receive the edge (22) of the sheet member (20) with the projection (40) snap-fitting into the opening (24), thereby providing a secure coupling between the sheet (20) and receiving member (30).</p> |
