Le piston (8) est logé avec mobilité de coulissement dans la partie de pot (9) en vue d'obtenir une course de pompe (b). La partie de pot (9) possède en outre des formations de fixation sur le côté de la paroi extérieure, destinées à la coopération de fixation avec une paroi intérieure du réservoir de stockage (2). La liaison par encliquetage (30) est configurée de manière renforcée par le fait ce que la liaison par encliquetage (30), par rapport à une section transversale longitudinale à travers le distributeur (1), est réalisée par deux bourrelets d'encliquetage (31, 32) qui sont espacés l'un de l'autre dans la direction verticale et qui font saillie dans le sens radial vers l'extérieur. L'invention vise à améliorer davantage un distributeur du type susmentionné en ce qui concerne la fixation, et se caractérise à cet effet en ce que les deux bourrelets d'encliquetage (31, 32) soient formés avec un arrondi d'insertion (37) du côté du réservoir de stockage, mais par contre, du côté de la pièce de tête par rapport à la section transversale longitudinale, avec une surface d'application (38) qui s'étend sensiblement horizontalement .
