Abstract: A bellows for use between two parts of a vehicle connected to each other by a pivot. Each of the facing ends of the vehicle parts, to which the bellows is connected, has a grooved formation extending in the circumferential direction of the bellows. Each end of the bellows carries a flexible but non-stretchable cable sized for accommodation within the grooved formation. In one version of the invention a cooperating toggle and turnbuckle arrangement interconnects the ends of the cable for tensioning the latter after it is placed in the grooved formation so as to attach the end of the bellows to one of the vehicle parts. In a second version the toggles are jointly operated by a common rotary disc.
