A connecting assembly for electrically connecting a ribbon cable in an aircraft. The assembly has a housing with a slot-shaped opening through which an end section of a ribbon cable can be inserted into a housing interior into a predetermined insertion position. The assembly has a first and a second engagement section which are arranged in the interior. The first engagement section is mounted such that it can be optionally moved between a first and a second position, such that by moving the first engagement section into its second position, the end section can be clamped tight optionally between the first second engagement sections and conductor tracks of the ribbon cable are then in contact with a corresponding number of electrical contacts provided on the first engagement section. In the second position, the first engagement section is releasably secured by a latching device.
