Abstract

A tube connection device for connecting motor vehicle tubes, a tube having a front element on at least one end, this front element being equipped with a frontal sealing surface. A fitting enclosing the tube is provided, which presses the frontal sealing surface against a connection surface of a connection element. At least one separate pressure element, which at least partially surrounds the tube, is provided between fitting and front element. The fitting acts on the front element through the pressure element and the sealing surface is pressed against the connection surface in this way.
