Hair clip comprising two shells (1, 3) provided with claws (5, 7) which are at the front of the clip and pivot relative to one another around two shell hinges (8-12) which extend in the same axial direction (A) at the rear of the clip, from a closure position in which the claws (5, 7) are brought together or even intersect, in order to grip the hair trapped by the claws, to an opening position in which the claws are spaced apart against the deformation of a resilient return means (13, 131, 132) which tends to return the shells (1, 3) to the closure position, and comprising a support plate (17) which is designed to receive for example a jewel and two lugs (19-22) which support the support plate (17) above the two shells (1, 3) in the closure position. The two lugs (19-22) are engaged with the two shells (1, 3), to the front of the axial direction (A) in the closure position, in order to give rise to a movement of lifting of the support plate (17) relative to the axial direction (A), in translation towards the rear, when the two shells (1, 3) pivot from the closure position to the opening position.
