A tensioning rail for an endless drive means, in particular for a chain drive of an internal combustion engine, comprises a support body and a sliding body arranged on the support body and having a sliding surface for contacting the endless drive means as well as at least one lubricant opening for wetting the sliding surface with lubricant. A press-on area provided on the support body and used for contacting a tensioning device has an inflow opening for the lubricant. A feed passage extending from the inflow opening through the support body and a lubricant passage extending in the longitudinal direction of the support body allow the supply of lubricant to the at least one lubricant opening.
