A connecting assembly for connecting to a fluid conduit in a fluid transfer system includes a ferrule-type connector having a first open end and a second open end. The first open end of the connector is operable to receive a fluid conduit therein. The second open end of the connector is operable to receive a washer and a flexible hose therein. The washer preferably has a concave cross-section and a central aperture receiving the fluid conduit to secure the connector to the fluid conduit when the washer is press-fit in the second open end of the connector and onto the fluid conduit.
