Abstract
The injector has a recirculating conduit with an end element having two rsses, each incorporating an opening; the backflow connector has a connecting element having a groove, and is fitted to the end element so that the groove corresponds with the openings; a C-shaped snap-on fastener has two arms with two portions for simultaneously engaging or releasing the recesses and, via the openings, also the groove; and the backflow connector is connected and disconnected by translating the fastener, which, however, remains secured to the injector at all times.
