QUICK TENSIONING DEVICE

Quick-release device (1) for at least partially muscle-powered two-wheeled vehicles (100) such as bicycles, with an axle unit (2) and a clamping device (3). The axle unit (2) has an axis (5) extending in an axial direction (4), a clamping device (6) at the first end (7) of the axle unit (2), and a fastening device (9) at a second end (10) of the axle unit (2). The clamping device (3) is suitable for mounting and dismounting the axle unit (2) on a two-wheeled vehicle (100). The clamping device (3) comprises an operating lever (12) and a clamping component (13) connected thereto. The clamping component (13) can be coupled to the axle unit (2) in a rotationally fixed manner and can be decoupled from the axle unit (2). The operating lever (12) of the clamping device (3) can be moved from an engagement position (14) that is rotationally fixed to the clamping component (13) to a rotational position (15) that is freely rotatable relative to the clamping component (13), while the clamping component (13) is coupled to the axle unit (2) in a rotationally fixed manner.
