The present invention refers to such car bodies
which are intended particularly for omnibuses,
and the roof, windows and wall sections of which
are carried by ,a framework of horizontally and
verticaliy extending, tubes rigidly connected to
each other, and the invention has for its object
an arrangement to secure 'wall sections consist“
