A connection arrangement for connecting two tube pieces of a crossmember for a vehicle has a first attachment element made of a first material, wherein the first attachment element is provided for a solid material-bonded connection to at least a first tube piece which comprises the first material. Furthermore, the first attachment element has a second attachment element which is fastened to the first attachment element, wherein the second attachment element consists essentially of a second material differing from the first material, wherein the second attachment element is provided for a solid material-bonded connection to a second tube piece which comprises the second material. Furthermore, a crossmember has such a connection arrangement.
