Detachable towing-bar for a passenger-car in which the ballrod with its free extremity can be coupled in an attachment-housing which is fixed to the vehicle and which at its front-end is provided with two contact-surfaces (4,5) against which in the attached position corresponding tensioning surfaces (2,3) on the ballrod are pressed and which provides a play-free tensioned attachment by means of a tensioning-part which is projected from the underneath of the ballrod and which is pressed outwards by a wedge-shaped head (10) of a sliding-part (11) which under spring-pressure can be displaced along its axis and which causes the tensioning part to be pressed against the lower-inside of the housing, thereby forcing the rear-end of the ballrod upwards until an inclined tensioning surface (6) on the upper rear-surface of the towing-bar presses against a corresponding inclined surface (7) which is located at the rear-end upper-wall of the attachment-housing. <IMAGE>
