The hair pin (100) includes two jaws (110,120) articulated around a spindle (150). The jaws are returned by a helicoidal spring (140) threaded on the spindle. A spring masking part is arranged between the two gripping parts (111,121) so as to cover the part of the spring threaded on the spindle. The masking part comprises two juxtaposed parts (130) each of which are fixed to the gripping part of a jaw. Each end strand (141) of the spring is supported against each corresponding part of the masking part so that the place of displacement of the end strands is located under the masking part. |
