Tube joint and component arrangement with tube joint

abA joint, especially of an exhaust system is provided for two axially adjacent ends of a tubular body, respectively. Each tube end has a ring collar projecting radially outwards. A centering ring is arranged axially between the tube ends and which has a plurality of collar segments in the radial outward direction. Some of the collar segments project axially on one side of the centering ring and axially overlap the ring collar of one tube end, while the other collar segments project axially on the other side of the centering ring and axially overlap the ring collar of the other tube end in the radial outward direction. A clamp axially and radially overlaps the ring collar and the centering ring in the radial outward direction.
