Abstract
A tubing coupling and a method for connecting tubing sections in which one tubing section is placed upon another tubing section in an overlapping manner. The first tubing section ( ) is enlarged in the cold state in the area ( ) where it overlaps, and the enlarged area is then placed over the second tubing section ( ). Subsequent heating of the enlarged area ( ) results in shrinkage of the first tubing section ( ) which produces a firm seating of the first tubing section ( ), for example a plastic suction tube as an air inlet tube, on the second tubing section ( ), for example a flange for attachment to the cylinder head of an internal combustion engine.
