Abstract
In a tension device for a nonskid chain, a winding reel is supported, so that it can rotate about its axis inside the housing and is prestressed in the winding direction and has a gear rim with teeth arranged along its circumference. A tension line that can be retracted into the housing can be connected to the winding reel, such that a ratchet in a first position blocks a rotational movement of the winding reel in the tension direction by engagement of the ratchet in the teeth. Areas free of teeth on the circumference of the gear rim of the winding reel alternate with areas with teeth.
