The invention relates to a clamping claw (1) for fixing a fuel injector (2) to a cylinder head (3) of an internal combustion engine, comprising a first bore (4) for receiving a clamping screw (5) and at least one other bore (6) for forming a high-pressure channel, said other bore (6) running substantially perpendicular to the first bore (4). According to the invention, the other bore (6) passes through the clamping claw (1) and extends from a first lateral surface (7) to a second lateral surface (8) which is substantially parallel to the first lateral surface (7) such that the other bore (6) can be connected to a bore (6), which is likewise used as a high-pressure channel, of another clamping claw (1) and/or a high-pressure pump via a high-pressure line (9). The invention further relates to an arrangement and a fuel injection system comprising such a clamping claw and to the use of a clamping claw as a high-pressure accumulator.
