This movement is reliably performed because the second engagement portion 83 of the movement restricting member 8 can spread the elastic deformation portion 68 and pass through the elastic deformation portion 68.

Abstract

L'invention concerne un ensemble aiguille de ponction comportant un corps ayant un tube d'aiguille, un protecteur se déplaçant entre une première position dans laquelle le protecteur couvre la pointe du tube d'aiguille et une seconde position dans laquelle la pointe est exposée, un corps comportant une section de déformation élastique et une section de support pour supporter le protecteur de manière mobile, et un organe de restriction de déplacement comportant une première section de mise en prise qui se met en prise avec le protecteur et comportant également une seconde section de mise en prise pouvant se mettre en prise avec la section de déformation élastique. Lorsque le protecteur se déplace de la première position à la seconde position, puis revient à la première position, le protecteur se déplace vers la première position conjointement avec l'organe de restriction de déplacement en prise avec le protecteur par l'intermédiaire de la première section de mise en prise. Lorsque le protecteur, à la première position, tente de se déplacer vers la seconde position, l'organe de restriction de déplacement fait contact avec le protecteur et la seconde section de mise en prise se met en prise avec la section de déformation élastique, restreignant ainsi le déplacement du protecteur.
