The top ledge (1) has one or more longitudinal grooves (11, 12) with side cut outs to make a contact for the characters (14). These include resilient sections (16) which adjoin the base of the longitudinal grooves under their own flexible tension. These resilient sections are tongues which are deformed by bending. The characters (14) have projections (15) on their sides which reach into the cut out sections of the longitudinal grooves.</p>
