Quick-release clamp (1) for detachably fastening an instrument, in particular a percussion instrument, to a holder, in particular for fastening to a rod-shaped holder with a smooth or at least partially structured surface, wherein the quick-release clamp (1) has a passage (14) for the holder, at least one movable clamping jaw (12) for changing the cross-section of the passage (14), at least one operating element (13) for influencing the position of the clamping jaw (12), and a housing (11), and the clamping jaw (12) is adjustable between a released position and a
rest position, wherein a spring element (15) is arranged between the housing (11) and the operating element (13) for holding the operating element (13) in a position,by which the clamping jaw (12) can be brought into the
rest position and / or locked, and no force is applied directly from the spring element (15) to the clamping jaw (12), and the operating element (13) is movable relative to the housing (11) and the clamping jaw (12) for breaking the positive locking connection between the clamping jaw (12), the operating element (13) and the housing (11), and for enabling the movement of the clamping jaw (12) into the released position, characterized in that , - at least two clamping jaws (12) are present; and - a positive locking connection exists in the
rest position between the operating element (13), the housing (11) and at least two of the clamping jaws (12) via a single operating element (13); and - the clamping jaws (12) are rotatable about a common axis (122) parallel to the
feedthrough (14).
