Beschreibung
Zusammenfassung:	The invention relates to a hydraulic tensioning device (1) for a chain drive having: a tensioner piston (9), which is guided in a receptacle (10) and has latching grooves (11) on its outside circumferential face; a locking element (12), which has two annular sections (13) and one open and one closed radial expansion (14a, 14b); and a clamping stop (15) and a sliding stop (16), which are spaced axially from one another, wherein the receptacle (10) has two axial extensions (17) which extend in the axial direction between the clamping stop plane (32) and the sliding stop plane (33). For greater durability, the sliding stop (16) comprises a sliding stop element (52), wherein the sliding stop element (52) has a transition section (53) and a functional section (54) which extends in the radial direction, and the sliding stop element (52) is supported on the axial extensions (17).
