Abstract

The present invention relates to a connection device (1) for at least one media line (2), such as for a urea-water solution for exhaust gas after-treatment in a motor vehicle having an internal combustion engine. The connection device comprises a connection part (4) having a socket (6) for the circumferentially sealed insertion of a line-side plug section (8), and retention means (10) for locking the inserted plug section (8) in place to prevent detachment. The retention means (10) is configured in such a way that starting from a normal operating position the inserted and locked plug section (8) can be moved over a specific travel path relative to the connection part (4) in opposition to a return force (F), in order to enlarge an internal volume inside the connection part (4) to which the medium is admitted.
