A connecting system connects two fluid-conducting components, such as first and second tubes, or a tube and a connecting part, or first and second pipes. The connecting system includes: a flange of a first component set back from a free end region of the first component； a flange of a second component formed at or behind a free end region of the second component； a securing device that engages a sleeve arranged at the second component so as to axially secure and align the first and second components with respect to one another； and a jacket that at least regionally covers the first component, the second component, and the securing device.
