Embodiment Construction
[0024] The shown pipe or hose connection 1 of the air intake system of a motor vehicle comprises a pipe connection 2 which protrudes, for example, from the filter housing of an air filter (not shown) and is formed by Plastic is integrally formed on the filter housing when the filter housing is manufactured. The pipe or hose connection 1 also includes a widened pipe or hose end 3 of an air inlet pipe or air inlet hose (not shown) made of plastic by blow molding, which pipe or hose end Inserted externally on the pipe connection 2 and fastened to the pipe connection 2 by means of a pipe or hose clip 4, as in Figures 1 to 4 shown in . The pipe or hose collar 4 is any suitable collar for this purpose, so it will not be described in detail here.
[0025] as best in figure 1 As can be seen in the figure, the pipe connection 2 has a longitudinal center axis 5 and a peripheral wall 6 coaxial to the longitudinal center axis 5 , which is delimited by a cylindrical inner peripheral su...

The present invention relates to a tube or hose connection structure which comprises a tube socket, tube or hose end (3) and a clamp ring. The tube or hose end is provided with an inwards projected first annular projection from the clamp ring. The width of the first annular projection is smaller than that of the clamp ring. The tube socket is provided with at least one second annular projection which project outwards. When the tube or hose end is inserted into the tube socket, the first annular projection exceeds the second annular projection. For easily inserting the tube or hose end that is obtained through blow-molding plastic on the tube socket, the invention suggests that one member in the first annular projection and the second annular projection extends along a plane which is vertical with a longitudinal axis of the tube socket and / or tube or hose end, and the other is crossed with a plane which is vertical with a longitudinal axis at two positions at least. Therefore when the tube or hose end is inserted on the tube socket and the first annular projection exceeds the second annular projection, the two annular projections do not contact simultaneously along the whole length.
Description
technical field [0001] The invention relates to a pipe or hose connection / connection unit according to the preamble of claim 1 , an air pipe or air hose according to the preamble of claim 7 and an air pipe or hose according to claim 14 The component with a pipe connection described in the preamble, the pipe or hose connection, the air duct or air hose and the component are used in particular for an engine air intake system. Background technique [0002] Intake ducts or hoses as well as charge air ducts or hoses are produced by blow molding and have ducts or hoses for plugging / slipping onto fittings of air filters, charge air coolers or the like Pipe ends. In such air intake lines or hoses and charge air lines or hoses, the pipe or hose ends are often fastened to the pipe connection by means of clips. In order to position the collar in the correct position on the pipe or hose end, the pipe or hose end can be provided with a collar seat on its outer circumference, which preve...
