− 前記プロテクタ支持体と針プロテクタとの間に設けられた圧縮ばねと、
− 前記圧縮ばねの作用に抗して前記針プロテクタを初期固定し、かつ解放方向における前記プロテクタ支持体に対する針プロテクタの変位によって解放可能な手段。
− 前記機械的ロック手段は、針プロテクタとプロテクタ支持体の第一者と一体化された弾性変形可能な少なくとも一つの舌部であって、前記舌部は、針保護キャップが存在している場合にプロテクタとプロテクタ支持体の第二者に軸方向に当接するロック(lock)位置と、針保護キャップが存在していない場合にプロテクタとプロテクタ支持体の第二者から遠ざかる非ロック位置との間を変位可能であり、各舌部は静止している際に非ロック位置まで延在し、そして各舌部は、針プロテクタの端開口に係合した針保護キャップの作用によって、それを変形保持する作用範囲を有し、
− 前記舌部は、針プロテクタとプロテクタ支持体の第二者に形成されたオリフィスに係合可能な突起を有し、
− 前記舌部はプロテクタ支持体の前端の延長部に延在している。
− 概ね管状の支持体20、
− 前記支持体20と同軸に配置され、これよりも大きい直径を有する保護スリーブ22、

− 前記プランジャを停止させ、注射器を保護ユニットに取付けるためのクリップ25
を基本的に含む。
支持体20は、注射器本体4の外径に実質的に等しい内径を有する実質的に円筒形の主部26を具えている。主部26は、直径的に対向した二つの長手方向の凹所26Aを有する。主部26は、主部26の直径よりも大きい内径を有する二次部28によって基端で拡張され、半径方向のショルダ29を形成している。二次部28は、注射器のカラー16の最大直径よりも大きい内径を有している。
容易に使用される。図示された保護ユニット2の部品点数は、三つに減少する。
− 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を一体化され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と一体化した部品としてもよい。
