Abstract
A screw connection device for connecting the flared ends of two pipes includes a nut, a screw and distance element which comprises a first recess or shape for accommodation of the flare at the end of a first pipe, and a second recess or shape for accommodation of the flare at the end of the other pipe. The nut and screw each accommodate one pipe end with the distance element between them with the recess at each end in sealing contact with the pipe flares. The nut and/or the pipe flare of the pipe end which in the connected state is accommodated in the nut comprise positive-fit elements, which positive-fit elements are designed such that the accommodated pipe end is secured against rotation relative to the nut.
