According to the invention each rail member (3, 4) includes at its front end a spring element and a holder element which are integrally connected to the rail members (3, 4) and are made of one piece with the latter. The spring elements and the holder elements are arranged on the rail members (3, 4) in such a way that the front wall (11) can be inserted between the spring elements (16) and the holder elements (17) and as a result of said insertion the front wall (11) will be secured to the rail members (3, 4 ).</p> |
