A tamper-proof cap for bottles comprising a cylindrical single piece injected in plastic material, including a cylindrical vertical base and a circular sealing belt connected to the cylindrical vertical base lower end, including a plurality of equidistantly spaced articulated blades adjacent to the lower presenting at least one anti-attrition flange radially inwards projected and a base, the flanges enabling a special effect in each blade during the process of application of the caps by high-speed machines. Specifically, the coupling of the cap occurs with low attrition because the contact area between the blades and the neck or collar of the neck is limited only to the flange. The cap is also designed to prevent the simultaneous unscrewing of the cap and of the sealing means, preventing the breakable elements from deforming instead of disrupting.
