Beschreibung
Zusammenfassung:	A medical delivery system such as a jet injection system comprises a medical delivery device (22) and a drug container (21) adapted to be mutually coupled along a main axis by a bayonet coupling. Said bayonet coupling comprises at least five joint couples, each couple comprising a lug (24) arranged on one of the container and the device and an associated support member (26) arranged on the other one of the container and the device such that at least two lugs of said at least five joint couples are formed as axially elongated lugs each having an axial length larger than its circumferential width. The specific coupling provided ensures improved handling, mechanical strength and reduced settling time during manufacture. L'invention se rapporte à un système médical d'administration (22) tel qu'un système d'injection par jet. Ledit système comprend un dispositif médical d'administration et un réservoir à médicament (21) adaptés pour être couplés ensemble le long d'un axe principal par un accouplement à baïonnette. Ledit accouplement à baïonnette comprend au moins cinq couples de joints, chaque couple comprenant une saillie (24), disposée sur le récipient ou le dispositif, et un élément de support associé (26), disposé sur l'autre parmi le récipient et le dispositif, de telle sorte qu'au moins deux saillies desdits cinq couples de joints ou plus se présentent sous forme de saillies axiales allongées, chacune ayant une longueur axiale plus grande que sa largeur circonférentielle. L'accouplement spécifique proposé assure une manipulation améliorée, une résistance mécanique améliorée et un temps d'établissement réduit au cours de la fabrication.
