これらソケットとプラグとの間に、連結状態を保持するリテーナとリテーナ係止部とで構成される連結保持手段を設け、このリテーナを前記プラグのノズル部を挟んで対向して一対設け、このリテーナの対向部の先端部内側に前記リテーナ係止部に係止される係止爪部を突出させて形成するとともに、これら1対のリテーナの係止爪部を前記ノズル部の外径と同等あるいは狭い間隔で設ける一方、これら1対のリテーナを前記ノズル部先端より高く形成したので、ノズル部を挟む1対のリテーナの内側に係止爪部を形成することで、係止の際には外側に移動させて初期状態では、ノズル部との隙間を小さくすることができるとともに、ノズル部の周囲を保護することができる。また、リテーナの高さをノズル部先端より高くして落下などの不測の事態でもリテーナでノズル部を保護することができ、直接ノズル部に損傷が及ばないようにすることができる。
このカップラー10は、ソケットS10と、このソケットS10と嵌合連結されるプラグP10とで構成され、例えばメタノール燃料電池の本体側にソケットS10が設けられ、メタノール容器としてのカートリッジ側にプラグP10が設けられ、互いを連通させて本体側に燃料を補充したり、カートリッジごと交換するのに用いられ、主要部は、金属材料と、非金属材料、例えばポリプロピレン、ポリフェニレンサルファイド、ポリアセタールなどの合成樹脂とで作られる。
