Abstract:
1. A connecting arrangement comprising: end sections of two fluid conduits to be connected to one another; a coupling element having an axis and an outer side surrounding the axis and an inner side surrounding the axis; wherein on a circumference of the end sections first securing ribs extending in the circumferential direction are provided, respectively; wherein on the inner side of the coupling element second securing ribs extending in the circumferential direction are provided proximal to each axial end of the coupling element; wherein the coupling element is coaxially coupled to the end sections in the coupled state of the connecting arrangement by being elastically expanded, wherein the second securing ribs lock behind the first securing ribs and the end sections are coupled seal-tightly with one another; wherein the coupling element is a circular cylindrical sleeve that has an outer circumferential surface that is completely closed circumferentially so as to provide protection for connection locations of the end sections, wherein on the inner side of the sleeve a stop rib is provided that extends circumferentially and limits an insertion depth of the end sections, wherein one of the end sections has a free end that rests against the stop rib and wherein the other one of the end sections has a shoulder resting against the stop rib, wherein the rib comprises elastically expandable material and is a monolithic part of the elastic sleeve segments, wherein the bending-resistant sleeve segments have an outer side provided with recesses in which recesses an elastically expandable material is arranged.
