An arrestable tensioning device 10 , in particular for a parking brake system, is described. The tensioning device 10 comprises an actuating device 20 , a tensioning element 40 coupled to the actuating device 20 for executing a tensioning motion, and a releasable arresting device 60 for the tensioning element 40 . The arresting device 60 has a first contour 70 coupled to the tensioning element 40 , as well as an arresting element 66 , which for arresting the tensioning element 40 interacts with the first contour 70 , i.e. for example, is brought into engagement with the first contour 70 . A lagging element 64 is provided, which upon a reversal of motion of the first contour 70 follows on after a time delay and in said case is movable relative to the first contour 70 back and forth between a first relative position enabling e.g. an engagement of the arresting element 66 into the first contour 70 and a second relative position preventing an engagement of the arresting element 66 into the first contour 70.
