Abstract

A charge-air hose assembly includes a charge-air hose (2) for connecting to a pipe stub (4). The charge-air hose (2), in the assembled position, is pushed into the pipe stub (4) in such a way that overpressure occurring in the charge-air hose (2) presses the charge-air hose (2) radially outward against the radial inner wall (6) of the pipe stub (4). The charge-air hose (2) is assigned a latching device which, during the insertion of the charge-air hose (2) into the pipe stub (4), latches with the pipe stub (4) so as to axially fix the charge-air hose (2) to the pipe stub (4) in a predetermined axial position of the charge-air hose (2) relative to the pipe stub (4).
