Abstract
A tensioning device for a flexible driving means, in particular a chain tensioner for a timing chain of an internal combustion engine, with a housing, a tensioning piston guided in a piston bore of the housing and a latching element arranged outside on the housing, is provided. A latching profile is provided on the front region of the tensioning piston in the tensioning direction. The latching element has at least one spring arm protruding over the housing in the tensioning direction, which engages the latching profile of the tensioning piston outside of the housing. The latching element for the delimitation of the free working range between a front end-stop and a rear end-stop in and against the tensioning direction is arranged movably on the housing.
