A machine element is provided that includes, but is not limited to a clamping element without a slit, which is incorporated into a receiving area of the machine element. The clamping element has an opening for accommodating a shaft, and can be twisted against the machine element. A support sleeve is arranged radially outside relative to the clamping element. This makes the machine element easy to manufacture, convenient to use, and allows the absorption of high levels of force.
