Abstract

This invention relates to a coupling device to connect two tubular elements, preferably a hose with a tube, with one male coupling element (3) and one female coupling element (5) that are formed so that they can be inserted in one another and can be locked by means of an expandable split clip (33). An axially movable release device (35) interacts with the split clip to release the lock. The invention is characterized by the fact that the release device (35) has an indicator element which indicates a connection between the two coupling elements (3, 5).
