[origin: EP0821115A2] The support structure has a number of parallel support beams (1). Each of the beams has a vertical surface incorporating openings for reception of plug-in tongues (10) at the ends of crossbeams (2). The free end of each plug-in tongue has a stamped out retaining tongue (14) which is bent to engage the rear edge of the reception opening after insertion. Each plug-in tongue is double layered, with the sheet metal layers joined together in the section from which the retaining tongue is stamped out.
