A clamping holder with a housing having a fixed clamping jaw, a push/pull bar through the housing and a movable clamping jaw. Spacings (A) of the free ends of a gripping handle and of a drive lever from the push/pull bar being approximately equal. Contour lines of the backs of the gripping handle and the drive lever being convexly rounded along the direction of their extent and respectively running on imaginary arcuate lines. The contour lines extend radially outward over the entire gripping zone up to the free ends and, in the region of the free ends, leave the imaginary arcuate lines toward their center points. The length of the radii of the arcuate lines being at least 70% of the spacing (A) and at most 200% of the spacing (A).
