CONNECTING UNIT

A connecting unit for connecting two exhaust gas-carrying assembly units of an exhaust system of an internal combustion engine, includes a ring washer-shape connection element (26) with a connection side (42), which is to be positioned to face a counter-connection element (24) to be connected to the connection element (26) or/and in contact with the counter-connection element (24), and a passage opening (28), which is bordered by an inner circumferential surface (36) of the connection element (26). The connecting unit further comprises a connection pipe (30), which is inserted into the passage opening (28) and extends in the direction of a pipe longitudinal axis (L). The connection pipe (30) is connected to the connection element (26) in the area of the inner circumferential surface (36) by welding, or/and the connection pipe (30) projects with a centering section (40) on the connection side (42) of the connection element (26). 本发明涉及一种连接单元，该连接单元用于连接内燃机排气装置的两个废气引导组件，该连接单元包括具有连接侧(42)和穿过开口(28)的环盘状的连接元件(26)，该连接侧应
