The invention relates to a clamping device (1) for fixing a wheelchair drive unit to a wheelchair frame. The clamping device (1) comprises a lever element (4), a first clamping jaw (2), a second clamping jaw (3) and a clamping jaw holder (5). The first clamping jaw (2) and the second clamping jaw (3) are movably mounted on the clamping jaw holder (5) via a jaw path (D0-D2) between an open position (D0) and a closed position (D2). The lever element (4) is movably coupled to the first clamping jaw (2) and the second clamping jaw (3) via a lever path (SH) such that a movement of the lever element (4) along the lever path (SH) causes the clamping jaws (2, 3) to move along the jaw path (D0-D2). A transmission arrangement couples the lever element (4) to the first clamping jaw (2) and the second clamping jaw (3) in such a way that, starting from the open position (D0) of the clamping jaws (2, 3), moving the lever element (4) by half the lever path (SH/2) causes the first clamping jaw (2) and the second clamping jaw (3) to move by more than half the jaw path (D0-D2/2) in the direction of the closed position (D2) of the clamping jaws (2, 3).
