前記注射プランジャは、注射プランジャを停止させるためのストップクリップを含み、前記ストップクリップはプロテクタ支持体により担持されかつ前記注射器本体の延長内に注射プランジャの移動路を形成し、その最小分部は前記注射プランジャの共通部の部分よりも大きくかつ前記注射プランジャのショルダの部分よりも小さい、ことを特徴とする。
−概ね管状の支持体20、
−支持体20と同軸に配置されかつた支持体20よりも大きい直径を有する保護スリーブ22、
−ばね24、および
−プランジャを停止させかつ保護ユニットに注射器を取り付けるためのストップクリップ25を含む。
・ 上述の実施形態とは異なり、保護スリーブ22のスタッド54及び/又はフランジ50を一体化した一つの部品として形成せずに、これらをスリーブ22に付加するようにしてもよい。
・ 前述の装置とは逆に、スタッド54をプロテクタ支持体20の外面上に設け、ガイド溝36を保護スリーブ22に形成してもよい。
・ 支持体20を注射器本体4とワンピースで形成してよい。
