Claim:
A connection arrangement including superimposed layers of material, characterised in that a pin ( 1 ; 1 ′; 1 ″) is provided with a head part where said head part is a head ( 2 ) or a head arrangement ( 2 ″), and engaging positions (s 1 , s 2 , s 3 , s 4 ; s 1 ″, s 2 ″, s 3 ″, s 4 ″) along part of the length of said pin for the attachment of a retaining element ( 3 ), where said pin is pushed through the layers of material (A, B) or a hole in the layers of material, and the layers of material are located between said head part and said retaining element, said pin includes a pin skeleton (SK 1 , SK 1 ″) coated with an outer material by moulding or injection moulding, said head part includes a head part skeleton where said head part skeleton is a head skeleton (SK 2 ) or head-arrangement skeleton (SK 2 ″) coated with an outer material by moulding or injection moulding; and said retaining element ( 3 ) includes a retaining-element skeleton (SK 3 ) coated with an outer material by moulding or injection moulding, where material of said pin skeleton, head part skeleton, and retaining-element skeleton is more resistant to heat than said outer material, said pin skeleton (SK 1 , SK 1 ″) has a main shaft (TR 1 , TR 1 ′) extending continuously over the length of said pin ( 1 ; 1 ′), with rungs (C 1 , C 2 , C 3 , C 4 , C 5 , C 6 , C 7 , C 8 ) projecting laterally from said pin; said rungs have ends; said engaging positions (s 1 , s 2 , s 3 , s 4 ; s 1 ″, s 2 ″, s 3 ″, s 4 ″) are formed between said ends of said rungs, said retaining element ( 3 ) engages an end of said pin and in an engaging position, said pin skeleton, said head part skeleton, and said retaining element skeleton are connected and remain connected following removal of said outer layer by burning or melting of said outer layer.
