<p>Connection arrangement comprises pin (1) with head part and engaging positions. The head part is head (2) or a head arrangement. The engaging positions are along part of its length of pin for the attachment of retaining disk (3). The pin includes pin skeleton (SK1). The head part includes head part skeleton (SK2). The retaining unit includes retaining disk skeleton (SK3). The skeletons are coated with outer material by molding or injection molding. The skeletons are more resistant to heat than the outer material. The material layers are located between head part and retaining disk. The pin skeleton has main shaft extending continuously over the length of the pin with rungs projecting laterally from the pin. The rungs have ends. The engaging positions are formed between the ends of rungs. The retaining disk engages an end of the pin and in engaging position. The skeletons are connected following removal of the outer layer by burning or melting the outer layer. The pin is pushed through the material layers or hole in the material layer. A flange is on a pin between the section and material layers. The pin has saw-tooth contour in imaginary lengthwise section with engaging positions formed by gaps between the teeth. The saw-tooth profile has rising and falling tooth flanks. An independent claim is included for retaining disk.</p> |
