Abstract: A disposable connector for mating a dialysate source container to a dialysis machine comprises a body defining two ports and a collar disposed around one of said ports. The collar of said connector includes a stepped inner surface to seat a seal, a grip ring, and a retaining ring. The seal provides a fluid tight connection with a dialysate source container, whereas the grip ring is embedded in a stem of the dialysate source container so as to mate the connector to the container. The collar also has a series of windows and protrusions interspersed within the windows, which protrusions engage the retaining ring so as to secure the seal, the grip ring and the retaining ring on the stepped inner surface of the collar.

Abstract: A dialyser connector comprising a main body and a sliding clip. The main body defines a cavity. The main body has a tube end and a dialyser end, with at least one aperture and a pair of ramps provided in a central portion between the tube end and the dialyser end. The sliding clip has a tube end and a dialyser end connected by a spine running along the top of the sliding clip. The sliding clip has a pair of flexible wings extending in an arc from the spine and a pair of arms extending in an arc from the spine, the pair of arms having at least one projection extending radially inward. The dialyser connector has a locked condition in which the at least one projection extends into the cavity of the main body and an unlocked conditions in which the at least one projection is withdrawn from the cavity of the main body, and wherein the at least one projection is biased to locked condition by action of pair of flexible wings on the pair of ramps.
