ABSTRACT:
For fastening a cover part at a frame part in which both parts have at least a metallic frame structure, spherical segments formed out of the frame part with fasteners in the form of balls are provided while the counter fasteners are constructed as collars which are components of the cover part and extend angularly bent in the direction of the frame part. After inverting the collars over the balls, each collar is pressed flat by a predetermined amount under straightening during a pressing operation in which the frame part serves as supporting surface so that at the end of the deformation operation, the collar is supported at the ball.
