Claim 0:
1. A connecting device for pipelines, the connecting device comprising: a connecting body with a receiving opening for a pipeline with a line end to be inserted in an insertion direction and a retaining ring seated inside the receiving opening for securing of the inserted line end against withdrawal, wherein inside of the connecting body there is a sleeve-shaped release element seated in an axially displaceable manner such that due to an action on the retaining ring, the securing of the inserted pipeline is terminated, in which by an insertion of the release element in the insertion direction, the retaining ring is elastically deformable in the region of retaining teeth to release the line end in which actuation sections of the release element act against the retaining ring, wherein the release element includes a ring part on which snap-in arms separated from each other by longitudinal slots are formed, wherein the ring part is perimeter sealed and defines a ring opening and can be sealed at an outer perimeter by an outer perimeter gasket against an interior perimeter wall of the connecting body and can be sealed at an interior perimeter in the region of the ring opening by an interior perimeter gasket against the inserted pipeline, wherein in an assembled state of the connecting device, in the interior perimeter region of the ring part of the release element, the outer perimeter gasket can be deformed from a sealing position such that between the outer perimeter gasket and the opposing, interior perimeter wall of the connecting body, at least one leakage gap is formed in the interior of the connecting device by an interior pressure of the pressurized medium flowing in the pipeline, and the release element is a materially bonded two-component part composed of the ring part and the outer and interior perimeter gaskets, wherein the outer and interior perimeter gaskets being formed of a more elastic material than the ring part.
