The device has flat housing parts (2, 3), which include a number of insertion openings arranged parallel to one another in a plane, where a side piece of an angle key is held in the openings in a friction-locked manner. The housing parts consist of elastic material plastic or rubber, and are connected with one another by a film hinge. The housing parts and the film hinge form a material integrative body, where the housing parts are pivotable from a parallel position to an elongated position. |
