Abstract

This invention is related to a moulding device (90; 92; 95; 98; 100; 110) arranged to be positioned inside a tubular member (17). The moulding device (90; 92; 95; 98; 100; 110) comprises a second closing part (1), a shaft (6) loosely connected to the second closing part (1) and able to glide snugly through an opening in a first closing part (7, 8). When inserted into the tubular member (17), the moulding device (90; 92; 95; 98; 100; 110) defines a chamber together with the inner surfaces of thereof. To form a cast, this chamber is filled with moulding material which thereafter cures. To remove the cast and the moulding device (90; 92; 95; 98; 100; 110) from the tubular member, a drawing force is applied to the first closing part (7, 8), which provides a pulling out of the rest of the moulding device (90; 92; 95; 98; 100; 110) and the cast.
