ABSTRACT:
In a tensioning device for tensioning lines having a drive element for the tensioning line, the drive element is coupled to a ratchet wheel which can be set into rotary movement by a pivot lever with a drive pawl. The directionally oriented notches of the ratchet wheel are shaped so that the pivot lever can be operated in an ergonomically favorable direction during tensioning of the tensioning line. This is made possible in that the notch back of the notch of the ratchet wheel which cooperates with a blocking mechanism in its blocking or detent position is remote from the free end of the pivot lever.
