Abstract
The invention relates to a tensioning device () for chains, having a spindle body () which is provided with at least one spindle thread (), and with at least two coupling elements (), wherein at least one coupling element () comprises a coupling thread () screwed to the spindle thread (), and with a securing element () which is embodied to be transferable from a release position, in which the coupling thread () can be rotated with respect to the spindle thread (), to a securing position, in which a rotation of the coupling thread () with respect to the spindle body () is blocked in a form-fitting manner. To provide a tensioning device with an easily operatable and secure release protection, the tensioning device () comprises at least one securing element () which creates a positive rigid body coupling between the at least one coupling element () provided with a coupling thread () and the spindle body () in the securing position.
