Abstract:
1. A turnbuckle for an anti-skid chain that can be mounted on a wheel of a vehicle, comprising: a housing; and a tension cable that can be pulled through a housing opening into the housing, wherein the tension cable is connected inside the housing to a winding roll that is pre-stressed in a winding-up direction and mounted so the winding roll can be rotated about an axle of the winding roll, wherein a ratchet wheel with at least one ratchet catch is provided on the winding roll and the tension cable can be blocked against a direction of tension by the ratchet catch engaging with the ratchet wheel, and wherein the ratchet catch is moved at least incrementally outwards from an idle position when the wheel is stationary, in which the ratchet catch is not in engagement with the ratchet wheel and the tension cable is not blocked, under the action of the centrifugal force upon rotation of the wheel, and this movement effects an engagement of the ratchet catch with the ratchet wheel.
