Beschreibung
Zusammenfassung:	The invention relates to a hydraulic tensioning device (1) for a chain drive, having a tensioning piston (9) which is guided in a receptacle (10) and which, on its outer circumferential surface, has detent grooves (11), and having a detent element (12) which has two ring-shaped sections (13) and two radial extensions (14), wherein the detent element (12) can be placed in engagement by means of the two ring-shaped sections (13) with one of the detent grooves (11), and having a clamping stop (15) and a slide stop (16) which are axially spaced apart from one another. To simplify the structural design and the installation of the detent element (12), the receptacle (10) has two axial elongations (17) which extend in an axial direction between the clamping stop plane (32) and the slide stop plane (33), wherein the two axial elongations (17) and the tensioning piston (9) do not enclose the two radial extensions (14), and wherein one of the two radial extensions (14) has a constriction (45) and an interruption (35) of the detent element (12).
