Sleeve clamps MM of die-cast aluminum have a split clamping point with round or square cross-section that has been partially machined by cutting methods.
The bore at the clamping point is arranged in the plane parallel to the outer surfaces of the sleeve halves. It receives typically available construction tubes via multiple ribs in the cross-section of the bore.
At the screw points, hex socket cap screws or adjustable hand levers reduce the bore cross-section for clamping.
Adjustable hand levers are intended for repeated, tool-free clamping. Under the designation HSK, these are available separately for individual use and in other designs. Compared with the tool-operated hex socket cap screw, the clamping force achievable with an adjustable hand lever is lower due to the shorter lever length.
