ABSTRACT:
A method for closing a non-circular opening in a plastic intake pipe of an internal combustion engine with a cover having a shape adapted to that of the opening includes the step of introducing the cover through the opening from outside the pipe by tilting the cover relative to the opening. The cover is then tilted within the plastic intake pipe to such an extent that the cover completely covers both the opening from the inside in a form-locking manner and an edge region of the plastic intake pipe which surrounds the opening.
