Abstract
A connecting device for pipelines or hose lines with a threaded body and with a pipe-like end piece which can be inserted into a receptacle formed on the threaded body and which can be fitted therein by means of a swivel nut screwed onto the threaded body, wherein the receptacle of the threaded body has the shape of a widening cone and the circumferential surface of the end piece that engages in the receptacle has a conical design, is characterized in that the circumferential surface () of the threaded body () that bears the external thread () has, in the direction of the front end of said surface, an inclined profile directed opposite to the cone of the receptacle (), and the swivel nut () has, with its surface () bearing the internal thread (), a profile complementary thereto, and the external thread () and internal thread () are designed as tapered threads in such a way that a radial force emanating from the tapered thread with the swivel nut () screwed on is directed opposite to the radial force exerted, with the connecting device mounted, by the conical end piece () onto the receiving cone () formed in the threaded body ().
