A gooseneck on a truck 3 is designed for releasable connection to a trailer 1 and is provided at its free end underneath with a knob 5 for engaging with a collar 6 in the bottom of a neck opening in the trailer. In order to ensure the engagement between the knob 5 and the collar 6 regardless of wear and tear and relative movements, a lamella 7 preferably in the form of a double- arm lever is arranged to pivot at the free end of the gooseneck 4, so that it can be brought against the top of the neck opening, preferably by means of a hydraulic cylinder 9. <IMAGE> |
