1. A fuel tank including a container wall having at least two opposite wall sections and a stiffening device situated between the two opposite wall sections, characterized in that the stiffening device has at least one connecting strut, each end of which has a strut profile section, which engages with a complementary wall profile section in each on the two opposite wall sections of the container wall in a tension-resistant manner in such a way that the connecting strut absorbs compressive forces acting on the container wall, wherein each strut profile section at the ends of the stiffening device face in a lateral direction such that strut profile sections are connected to the complementary wall profile sections of the container wall by laterally displacing stiffening device in the lateral direction, wherein the at least one connecting strut includes a flat body having a wall thickness of 2 mm to 20 mm extending between the end strut profile sections, which is provided with a plurality of reinforcing ribs extending transversely to its flat side to beyond the strut profile sections.
