Selon l'invention, l'espaceur (29) est formé de deux parties, à savoir un tampon (39) composé d'un composant souple élastiquement flexible et un socle (41) composé d'un composant dur rigide. Dans un état de fabrication non déformé, la hauteur de construction (h) de l'espaceur (29) est supérieure à la dimension de fente de la fente de montage (27), de telle sorte que dans la position de montage l'espaceur (29) est soutenu entre la pièce de tôle de fond (10) et la paroi supérieure de la batterie (15) par une déformation élastique du tampon (39).
