• wherein the casing encloses a connection space (27) and has an inner surface facing the connection space (27),
• wherein the casing (24) comprises, at the topmost edge, an inlet opening (28) that accepts a lower part the cartridge (1) within the connection space (27),
• wherein the outlet opening (29) that extends through the bottom wall (25) has an inward facing edge that, with the lower part the cartridge (1) within the connection space (27) and the teatcup liner (7) sealed in tight abutment against the milking conduit (4), holds with snapping-in engagement an outwardly facing groove (41) of the milking conduit (4) with the milk conduit (4) extending through the outlet opening (29), and
• wherein the casing (24) comprises, on the inner surface facing the connection space (27), a first locking element (31) that, when engaged with a corresponding second locking element (32) on an outer surface of the sleeve (6) of the cartridge (1), releasably locks the cartridge (1) within the connector (2).
