PURPOSE: A snap connection for comprising two tube ends and a double-connection element is provided to apply for intake or charging area of an automobile engine, especially for turbo-charged engines on the charging areas. CONSTITUTION: A snap connection for sealed and releasable connection comprises a second tube end(20), spring arms, a first outer stop projection(14) on a first tube end(10), a first elastically deformable ring connected with the spring arms, and two first inner stop cams on the first ring cooperating with the first outer stop projection is characterized by a second outer stop projection(23) on the second tube end, a second elastically deformable ring connected with the spring arms with distance from the first ring, and two second inner stop cams on the second ring cooperating with the second outer stop projection. Both rings with the stop cams connected to one another via the spring arms form a double-connection element(30) separable by and on both tube ends, which is made from a plastic injection molding part. The first tube end is made by extrusion blow-molding, directly assembled with the second tube end, and is a metal or plastic connecting piece, and accordingly, the connection is fixed in a sealed position after the snapping of the double-connection element.
