Abstract
Disclosed is a ball-shaped coupling (10) for coupling a tractor to a trailer. Said ball-shaped coupling (10) comprises a coupling ball (12) and a ball socket (16) that can be coupled thereto. The ball socket (16) surrounds a section of the coupling ball (12) and rests against a contact surface (24) of the coupling ball (12) by means of an opposite contact surface (22) in the coupled state so as to form a common contact area (28). According to the invention, a seal (38) which seals the contact area (28) towards the environment is provided between the coupling ball (12) and the ball socket (16).
