Abstract

A hydraulic tensioning device for a chain drive, including tensioning piston, which is guided in a holder and which has locking grooves on the outer peripheral surface of the tensioning piston, and including a locking element, which has at least two annular sections and at least two radial extensions, wherein the locking element can be brought into engagement with one of the locking grooves by the at least two annular sections, and including a clamping stop and a sliding stop, which are axially spaced apart from each other. In order to simplify the design, the holder has at least two axial extensions, which extend in the axial direction between the clamping stop plane and the sliding stop plane. The at least two axial extensions and the tensioning piston do not enclose the at least two radial extensions.
