A coupling device (10) comprises a male coupling member (12) and a female coupling member (14), each having outwardly extending ends which carry male (68) and female (144) sealing elements, respectively, formed with mating, spherical-shaped surfaces (70, 148) which are effective to force solvent or coating material which may have collected thereon into passageways formed in each of such sealing elements or onto facing surfaces of the coupling members to substantially prevent contamination of new coating material flowing through the coupling device after a cleaning and/or color change operation has been performed. Un dispositif de couplage (10) comporte un moyen de couplage mâle (12) et un moyen de couplage femelle (14), chacun ayant des extrémités s'étendant vers l'extérieur et portant, respectivement, un élément d'étanchéité mâle (68) et un élément d'étanchéité femelle (144), formés avec des surfaces sphériques (70, 148) qui se correspondent, qui sont réalisées de manière à forcer un solvant ou un produit de revêtement, qui aurait pu s'y recueillir, dans des passages formés dans chacun des éléments d'étanchéité ou sur les surfaces se faisant face des moyens de couplage, afin d'empêcher sensiblement la contamination d'un nouveau produit de revêtement circulant dans le dispositif de couplage après une opération de nettoyage et/ou de changement de couleur.
