摘要 A method for jointing at least two plastic elements in a liquid- and/or gastight manner, whereby an edge of a first plastic element is at least partially placed in an opening of a second plastic element, the edge of the first plastic element being folded over an edge of the opening of the second plastic element under plastic deformation, using pressure means, whereby the edge of the first plastic element is pressed against a curved butting face of a pressure body being placed in the second plastic element at the opening thereof, that the edge of the first plastic element along the butting face is pushed radially outward and over the edge of the opening of the second plastic element, that the edges of both plastic elements are pressed together by exerting pressure on both sides of the edges, and that use is made of a sealing ring at least partially between the edges.
