A hose clamp comprising:
- a clamping band having ends which overlap one another in a closed condition of the clamp thereby forming an inner and an outer clamping band portion,
- wherein the outer clamping band portion terminates at one of the ends in a tongue which has a width reduced with respect to that of a main portion of the outer clamping band portion,
- wherein the tongue carries on an inner side, at least one inward facing projection cooperating with at least one outward facing projection provided at the inner clamping band portion for tightening the clamp,
- wherein the inner clamping band portion has retainers which are closed at their outer sides and surround the tongue at least in part, and
- wherein the retainers are stamped from the material of the clamping band, and material webs left between adjacent ones of the retainers are enlarged in width thereby reducing gaps in the clamping band formed by the stamping so that the gaps are smaller than the retainers.
