    • 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 (12) of the threaded body (10) that bears the external thread (30) has, in the direction of the front end of said surface, an inclined profile directed opposite to the cone of the receptacle (11), and the swivel nut (17) has, with its surface (18) bearing the internal thread (31), a profile complementary thereto, and the external thread (30) and internal thread (31) are designed as tapered threads in such a way that a radial force emanating from the tapered thread with the swivel nut (17) screwed on is directed opposite to the radial force exerted, with the connecting device mounted, by the conical end piece (13) onto the receiving cone (11) formed in the threaded body (10).
    • 一种用于具有螺纹体和管状末端件的管道或软管线的连接装置,其可以插入形成在螺纹体上的容器中,并且可以通过旋拧在螺纹体上的旋转螺母装配在其中, 其特征在于,所述螺纹体(10)的圆周表面(12)具有锥形设计,其特征在于,所述螺纹体(10)的圆周表面(12) 承载外螺纹(30)在所述表面的前端的方向上具有与所述容器(11)的锥体相对的倾斜轮廓,并且所述旋转螺母(17)具有其表面(18), 轴承内螺纹(31),与其互补的轮廓,并且外螺纹(30)和内螺纹(31)被设计成锥形螺纹,使得锥形螺纹与旋转螺母(17)发出的径向力 )是dir 其与通过锥形端部件(13)安装在形成于螺纹体(10)中的接收锥体(11)上的径向力相反。
