Abstract

A tube arrangement comprises a first tube and at least one second tube, the first tube and the second tube being arranged in relation to one another with an offset transversely with respect to the longitudinal direction of the tubes and with a partial overlap region in the longitudinal direction of the tubes, so that a first end of the first tube is arranged at a side of the second tube and a second end of the second tube is arranged at a side of the first tube. The tube arrangement has, further, at least one connection element which fixedly connects the first tube and the second tube to one another in the overlap region. The connection element has a first end wall and a second end wall spaced apart from the first end wall in the longitudinal direction of the tubes, which end walls extend, in the overlap region, between the tubes transversely with respect to the longitudinal direction of the latter and are fixedly connected to these, and two longitudinal walls which are spaced apart from one another transversely with respect to the longitudinal direction and which extend in the longitudinal direction of the tubes from the first end wall to the second end wall and are fixedly connec…
