<p>The injector (5) has a recirculating conduit (12) with an end element (13) having two recesses (33), each incorporating an opening (43); the backflow connector (16) has a connecting element (17) having a groove (42), and is fitted to the end element (13) so that the groove (42) corresponds with the openings (43); a C-shaped snap-on fastener (34) has two arms (36) with two portions (38) for simultaneously engaging or releasing the recesses (33) and, via the openings (43), also the groove (42); and the backflow connector (16) is connected and disconnected by translating the fastener (34), which, however, remains secured to the injector (5) at all times. <IMAGE> <IMAGE></p> |
