Abstract:
1. A connecting device for connecting a hose in a fluid-conveying system, the connecting device comprising: a nipple having a rotation-symmetrical hose-receiving section and, at a distance therefrom, an anti-twist section including a radially outward projecting annular bead that initially has a circular shape, the radially outward projecting annular bead extending radially outwardly beyond an outer radial diameter of portions of the nipple adjacent the anti-twist section of the nipple, and a compression sleeve that extends over the hose-receiving section and over the anti-twist section, the compression sleeve deformed in a non-circular manner to provide a positive-locking engagement with respect to a relative rotation in the anti-twist section, wherein the anti-twist section is a non-circular deformation of at least part of the nipple, and the radially outward projecting annular bead is deformed in a non-circular manner by the compression sleeve.
