The present invention refers to a device for tensioning a connecting element fastened to a component to be tightened, which comprises an engagement element having an engagement section receiving and holding the connecting element, a support element configured to support the device against the component, and an actuating unit having a fluid chamber for receiving a fluid, wherein the actuating unit is configured to manipulate a volume of the fluid chamber so as to move the engagement element relative to the support element. The device further comprises a vent opening fluid-communicatively connectable to the fluid chamber which is disposed in the region of the engagement section.

Device for tensioning a connecting element

The present invention refers to a device for tensioning a connecting element fastened to a component to be tightened, which comprises a fixation element for receiving and holding the connecting element; a support element for supporting the device against the component; and an actuating unit with a fluid chamber for receiving a fluid and a piston which is translationally guided in the fixation element. The actuating unit is configured for manipulating a volume of the fluid chamber by translationally actuating the piston so as to move the fixation element relative to the support element. Further, the device comprises a guiding unit for locking a relative rotational movement between the piston and the fixation element, wherein the guiding unit is arranged outside of the fluid chamber.
