Au niveau de l'ouverture d'aspiration se trouve une lèvre de récupération (92) échangeable et les deux demi-boîtiers (76, 78) présentent au voisinage de l'ouverture d'aspiration (82) respectivement au moins un élément de retenue (110, 114, 120, 122) et une section de retenue (98) de la lèvre de récupération (92) échangeable est disposée entre les éléments de retenue (110, 114, 120, 122) des deux demi-boîtiers. Pour apporter des améliorations à la buse d'aspiration (32) de sorte qu'elle est maintenue de manière fiable au niveau de l'ouverture d'aspiration (82), les éléments de retenue (110, 114, 120, 122) forment avec la section de retenue (98) respectivement une partie de prise.
