Abstract
A process and a device produces a linkage of a hollow cylindrical air/fuel ratio detector holder to an opening for the impingement of the air/fuel ratio detector, which is fastened into the holder, to an exhaust pipe equipped with exhaust gas. A desired finished shape is given through internal high-pressure remodeling of a blank pipe. During this process, internal high-pressure remodeling creates a contact surface on the exhaust pipe which is formed by a buckling. The contact surface is created to in the inverted shape of the contact contour of the casing surface of the holder so that a dimensionally stable linkage of an air/fuel ratio detector holder to an exhaust pipe is achieved simply.
