Output (English): In the present invention there is disclosed a clamp structure comprising a clamping band (11) made from band material of substantially constant thickness, and intended for tightening about an object to be fastened, whereby  clamping band (11) is provided with a tongue-like extension (30) at one end and an opening (21) performed at proximity of the other end of the clamping band (11) and in the plane thereof, whereby said tongue-like extension (30) and the opening communicate with each other for holding the clamping band (11) in tightened state. A pair of complementary sawtooth-like means are performed along the longitudinal edge surfaces of said tongue-like extension (30) and along the inner longitudinal surfaces of said opening (21), whereby said tongue-like extension (30) is provided with means to cause elastic engagement of its sawtooth-like means with the sawtooth-like means of the opening (21).
