A hose clamp having a resilient clamp body and a first tightening end and a second tightening end, said tightening ends overlapping each other, said tightening ends being bent substantially radially away from said clamp body; said clamp body being adapted and constructed to have a certain inside diameter in the clamping state and being able to be spread apart to a considerably greater diameter counter to its own spring force in the spread-apart state; said first tightening end being in the shape of an inverted U; said second tightening end being in the form of a protrusion, said second tightening end being disposed between the legs of the U of said first tightening end, a free end of said second tightening end being about at the radial height of the crossbar of the U of said first tightening end; wherein said first tightening end is bent back toward said second tightening end substantially at a tangent or in a circumferentially curved manner at a predetermined radial distance from said clamp body; wherein said tightening ends in the spread-apart state of said clamp body interlock with one another and in the clamping state are unlocked from one another; wherein a shackle is made by bending a tongue of said first tightening end radially from the outside inwardly; wherein the shackle at the free end of said first tightening end is bent at the end in the manner of a detent hook radially inwardly onto the clamp body, said shackle in the spread-apart state gripping the free end of the other tightening end lockingly from behind; wherein said detent hook has a considerably lesser width than the free end of said second tightening end; and wherein a generally U-shaped engagement opening for said detent hook is provided on the free end of said second tightening end.
