1. A hose clamp made of a clamping band (10) comprising band sections which overlap one another in a closed state of the hose clamp and on which hooks (12, 19) are arranged for closing the hose clamp, and a tightening device (15) arranged in an outer band section for tightening the hose clamp around an object to be clamped,
characterised in that the hooks (12, 19) are stamped out from the clamping band and each have a lug (21, 25) and a transverse surface (27, 32) facing transversely to a direction of the clamping band (10), wherein, in the closed state of the hose clamp, the lug (21) of at least one hook (12) arranged on the inner band section and the lug (25) of a hook (19) arranged on the outer band section engage over one another and a force transmission in a tightened state of the hose clamp occurs via the mutually contacting transverse surfaces (27, 32) of the hooks (12, 19).
