摘要

The coupling device (1) has an end fitting (2), which is arranged at a segment. The end fitting shrinks to a snap connection with a receiving part (6) arranged on another segment. The receiving part has an opening that has a reversibly changed cross section. A medium (10) is projected in the opening with which the cross section is changed. An independent claim is also included for a method for connecting two segments of a transmission unit.
