Patent ID: 8267435

Claim:
A charge-air hose assembly comprising: a pipe stub having a radial wall and a longitudinal axis defining an axial direction; a charge-air hose having a radial outer surface and being insertable into said pipe stub in a manner so as to cause an overpressure in said charge-air hose to press said charge-air hose radially outwardly against said radial wall of said pipe stub, said charge-air hose having an insertion end and said pipe stub having a contact region at said radial wall receiving said insertion end in contact engagement therewith when said charge-air hose is inserted into said pipe stub in said axial direction to an axial position; said insertion end having a cross section that is complementary in shape to a cross section of said contact region so as to cause said insertion end and said contact region to conjointly define a seal between said pipe stub and said charge-air hose at said axial position in response to said overpressure; a latching device for fixing said charge-air hose in said pipe stub at said axial position of said charge-air hose relative to said pipe stub as said charge-air hose is inserted into said pipe stub in said axial direction; said latching device including: a holder mounted on said outer surface of said charge-air hose; an annular spring disposed in said holder with said holder and said annular spring being insertable into said pipe stub as part of said charge-air hose; said annular spring being resiliently biased in an outward radial direction; and, said radial wall of said pipe stub having a slot formed therein for receiving said annular spring therein when said charge-air hose is inserted into said pipe stub causing said charge-air hose to latch with said pipe stub at said axial position.
