Zusammenfassung: | To produce mechanical links without additional measures the invention provides for the base (1), side walls (2) and rear wall (3) of a sheet casing to consist of a single, common piece of sheet. The side walls each have an incision (4) in the area of their upper rear corner and the rear wall has a bent edge (5) which on its sides presents hook-like projections (6). When the rear wall itself is folded upwards these click into place in the incision of the side walls. |
