<p>Together, two plates (6, 7), pivotably connected with each other via a film hinge (9), form a marker plate receptacle (1) in which a marker plate (5) is received. A tongue (3) is formed in one piece on the lower end of one of the two plates (7). It has a hook (12) which can be put over a wall (16) extending perpendicularly to the surface of the inside of the plate (7) and around a through-hole (2). Once the marker plate (5) has been inserted and the hook (12) of the tongue (3), on which a key (4) has been placed, has been put over the said annular wall (16), the two plates (6, 7) are folded together. The tongue (3) is then form-fittingly maintained between the two plates (6, 7) and the plates themselves are maintained by means of a form-fitting ridge formed on the annular wall (16), which extends through the through-hole (2) in the rear plate (6). The form fit is additionally improved by means of ribs (14) engaging grooves (15). (Figs. 1 and 2)</p> |
