Abstract

A tensioning device for a traction mechanism, particularly a belt or a chain, including a tensioning lever over which the traction mechanism is guided and on which a tensioning spring is disposed with one end thereof, the other end thereof being provided on a spring holder by which the tensioning device can be fastened to an external object. A holding pin (11) extends through the tensioning spring (4), with the pin at one end (11) thereof being disposed in a fixed position on the tensioning lever (2) and at the other end thereof having a locking section (22) disposed on a locking element (17) provided on a spring holder (6). The locking element can be adjusted between a locking position of the holding pin end (16), in which the tensioning device (1) is fixed in a position with the pretensioned tensioning spring (4), and a released position of the holding pin end (16), in which the holding pin (10) is axially displaceable in the locking element (17), and limited by a stop.
