The invention relates to a plastics pipeline comprising at least one pipeline end () and at least one support ring (). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring () remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section () runs through the support ring () and, as viewed radially, is pressed from the inside outward against the support ring (), wherein the pipe section () engages around the support ring (), such that the support ring (), with its outer surface, and the pipe section (), with its outer surface, are substantially in alignment.

A charge-air hose assembly includes a charge-air hose () for connecting to a pipe stub (). The charge-air hose (), in the assembled position, is pushed into the pipe stub () in such a way that overpressure occurring in the charge-air hose () presses the charge-air hose () radially outward against the radial inner wall () of the pipe stub (). The charge-air hose () is assigned a latching device which, during the insertion of the charge-air hose () into the pipe stub (), latches with the pipe stub () so as to axially fix the charge-air hose () to the pipe stub () in a predetermined axial position of the charge-air hose () relative to the pipe stub ().

A system for pre-positioning a hose clamp () on a hose end () includes: a) a fixing part (') which is connected non-releasably to an annular segment of the hose clamp () and is fastened to the hose end (), and b) one or more fixing parts (&#x2033;) which each have a U-shaped element which, fastened to the hose end (), is directed with its open side () to the hose surface. The web () connects the two U-legs () and extends axially and parallel to the hose surface. The U-leg (), which lies closest to the hose end (), has a connecting element () for attaching the U-shaped element to the end face of the hose end (). The U-shaped element is configured in such a way that the hose clamp (), which is pulled on to the hose end (), is fixed releasably in the intermediate space () of the U-shaped element by way of an annular segment of the hose clamp in such a way that the hose clamp () is released from the fixing when tightened. The fixing part () remains without function on the hose end () after the hose clamp () has been tightened.
