<p>The present invention relates to a fitting device ( 10 ) for a tube-shaped workpiece ( 27 ) for use in internal combustion engine facilities. The fitting device ( 10 ) has a basic body ( 16 ) for the reception of the tube-shaped workpiece ( 27 ), the basic body ( 16 ) being positioned in the opening of the laminar component ( 15 ) and at least a part of the basic body ( 16 ) essentially being movable in a plane which is oriented parallel to the plane of the opening. Furthermore, the fitting device ( 10 ) has a frame element which holds the basic body ( 16 ) and is supported on the opening edge of the laminar component ( 15 ). The fitting device ( 10 ) is arranged in such a way that it covers the opening of the laminar component ( 15 ) after reception of the tube-shaped workpiece ( 27 ).</p>
