  • Patent number: 5365955
    Abstract: The closure of a hair clip comprises two curvilinear pressure tangs which are mobile relative to each other in the longitudinal direction. Their end parts overlap to define an overlap area. The two tangs are linked together in the overlap area to form a continuous loop facing a baseplate of the closure. A hair clip incorporating a mount of this type is easily adjusted in position and the hair is better distributed within it.
