The tensioning elements are provided with relatively movable pistons which are nested one within the other, have a common pressure space and are accommodated in a cylindrical housing. The housing is provided with a fastening eye which extends axially parallel to the housing whereby the fastening eye is secured at an internal combustion engine housing part by a bolt. Oil is conducted to the pressure space between the pistons by way of the bolt.
