Abstract
In order to simply and economically fix to an internal-thread coupling (12) a pipeline (17) furnished with two slidable external-thread connections (15, 18), the invention contemplates fabricating the two external-thread connections (15, 18) together in the shape of one part only. At a predetermined screw-in torque, one external-thread connection (15) is torn off and as a result one pipeline end (16) is safely retained in the internal-thread coupling (12). The second external-thread connection (18) may be slid to the second end (21) of the pipeline and can fix the latter to a further internal-thread connection. The fixing means and methods contemplated by the invention are automation compatible and, upon fixing, protect the pipeline from being detached from the coupling through faulty handling.
