Abstract The invention relates to a tensioning device (1) for chains, having a spindle body (2) which is provided with at least one spindle thread (11), and with at least two coupling 5 elements (3, 4), wherein at least one coupling element (3, 4) comprises a coupling thread (3b, 4b) screwed to the spindle thread (11), and with a securing element (5) which is embodied to be transferable from a release position, in which the coupling thread (3b, 4b) can be rotated with respect to the spindle thread (11), to a securing position, in which a rotation of the coupling thread (3b, 4b) with respect to the spindle 10 body (2) is blocked in a form-fitting manner. To provide a tensioning device with an easily operatable and secure release protection, the tensioning device (1) comprises at least one securing element (5) which creates a positive rigid body coupling between the at least one coupling element (3, 4) provided with a coupling thread (3b, 4b) and the spindle body (2) in the securing position.
