Hair clip

A hair clip comprising:

• a curvilinear upper clamping arm including a tip formed at a front end of the upper clamping arm, two opposed side ears adjacent to a rear end of the upper clamping arm and each side ear having an aperture, a plurality of first elongated projections, and a plurality of second elongated projections disposed on a lower surface of the upper clamping arm, wherein the second elongated projections are shorter than the first elongated projections;
• a curvilinear lower clamping arm having a radius of curvature greater than a radius of curvature of the upper clamping arm, wherein a front end of the lower clamping arm abuts against an inner surface of the tip of the upper clamping arm;
• two opposed side brackets adjacent to a rear end of the lower clamping arm and arranged between said two side ears and each side bracket having an aperture,
• a single central elongated opening extending longitudinally from a position adjacent to the front end to a position adjacent to the two side brackets;
• a hinge assembly including a torsion spring disposed between the side ears and the side brackets and having a pin inserted through the aperture in each side ear and each side bracket and wherein the torsion spring is arranged to engage an inner surface of each side bracket;
• wherein, when opening and closing the hair clip, the curvilinear upper and lower clamping arms pivot via the hinge assembly;
• and
• wherein, when the hair clip is closed, the first elongated projections of the curvilinear upper clamping arm pass through the elongated opening of the curvilinear lower clamping arm, the second elongated projections of the curvilinear upper clamping arm do not pass through the elongated opening of the curvilinear lower clamping arm, and the front end of the curvilinear lower clamping arm abuts against the inner surface of the tip of the curvilinear upper clamp arm.
