摘要

The device (10) has a bearing body (12), and a tensioning lever (14) supported at the bearing body in a pivotable manner around a pivot axis (28). An operating unit (34) is provided for pressurizing an object with clamping force. A groove body (16) is arranged at a lower side (52) of the bearing body and inserted into a T-groove-shaped recess in a movable manner, where the groove body is arranged in a rotatable manner around more than 90 degrees. The operating unit has a threaded pin (36) that is pivotably arranged at the tensioning lever. Independent claims are also included for the following: (1) a spacing device (2) a method for manufacturing a device for tightening an object.
