Abstract: A holding clamp 1 for a curler 2 to hold a strand of hair 3 rolled up on the curler 2, wherein the clamp 1 has an elastic spring hook 6, 7 at each of the two ends 4, 5, and both of the hooks, each having an edge 8, 9, can be snapped in at both ends 10, 11 of the curler 2. The holding clamp 1 has a pressure spring device 12 between both hooks 6, 7; the pressure spring device induces a spring force F to at least a portion of a jacket area 13 of the curler 2. At least one injection molded leaf spring 14 is provided as a pressure spring device 12. In doing so, the leaf spring 14 is distorted so that it can be placed at the contours of the jacket area 13 with a gentle amount of pressure thus preventing the distortion of the rolled up strand of hair 3 (FIG. 4).
