Abstract

L'invention porte sur un groupe comprenant un premier système (1) et un second système qui sont distincts, chacun d'entre eux comprenant un col d'entrée (14) pour un pistolet d'alimentation en carburant, ainsi qu'une ouverture de passage (32) pour le carburant. L'un des systèmes comporte un ensemble de détrompage afin de permettre l'insertion d'un pistolet d'alimentation en carburant diesel dans ladite ouverture de passage (32) et d'empêcher l'insertion d'un pistolet d'alimentation en essence dans ladite ouverture de passage (32). L'autre système ne comporte pas cet ensemble de détrompage. Selon l'invention, chacun des deux systèmes comprend une pièce d'extrémité similaire (4, 5) pour recevoir un pistolet d'alimentation en carburant.
