Hair clip with annular springs

Hair clip comprising:

• a first jaw operable by a first opening lever to which it is attached in a first intermediate connecting area,
• a second jaw operable by a second opening lever to which it is attached in a second intermediate connecting area,
• hinge means connecting said first and second intermediate connection areas to enable pivoting of said first and second jaws relative to each other about a transverse hinge axis between an open position and a closed position,
• spring means for urging said first and second jaws towards their closed position, wherein:
• said hinge means include first and second perforated lugs respectively projecting beyond said first and second intermediate connecting areas and close together in the transverse direction along said hinge axis, third and fourth perforated lugs respectively projecting beyond said first and second intermediate connecting areas and close together in said transverse direction along said hinge axis but transversely spaced from said first and second perforated lugs with a stabilizing spacing E, and a coupling pin extending through the four perforated lugs to connect together said two jaws, and
• said spring means include two open annular springs disposed around said hinge axis and coaxial with each other, having a common transverse axis parallel to said hinge axis, their respective ends bearing in corresponding housings on outside surfaces of said intermediate connecting areas of said jaws in front of said hinge axis and their intermediate parts extending through corresponding openings in said opening levers and surrounding the two sets of perforated lugs between said levers.
