A composite compressed gas tank intended for a gas has an outer shell and a liner. The liner is enveloped by the outer shell and is made of a light metal, in particular, aluminum or an aluminum alloy. The gas tank has an in-feed and discharge port, in which is inserted a closing element that has at least one channel for infeeding and/or discharging gas and that is connected directly or indirectly to the liner by a welded joint, and a connecting line made of a steel material is connected to the channel or channels of the closing element. A transition element is provided, of which a first end segment is made of a light metal, in particular aluminum or an aluminum alloy, and is welded either to the liner or to the closing element, which is made of a light metal, in particular aluminum or an aluminum alloy; and the other end segment of this transition element is made of a steel material. The other end segment is welded either to the closing element, which is made of a steel material, or to the connecting line, which is made of a steel material.
