Abstract

The semi-trailer (3) has a towing arm (2) with a connecting pin (4). Near the pin is a bolt which moves between a position folded away in the arm and one out of it. The bolt can be locked in the "out" position. The pin can slide in a sleeve fitted inside the tractor arm and the bolt locking mechanism can be fitted inside the bolt, and eccentric to it. The sleeve has an internal finger lodging in a longitudinal groove in the bolt and can have recesses for bolt locking.
