A fluid transfer device may include a body member and a fluid transfer tip, wherein the fluid transfer tip may include a tapered friction fitting for a corresponding hub. The fluid transfer device also may include a disconnecting member having a front portion and a rear portion and engagement features operating between the disconnecting member and the body member. The engagement features engage with one another to inhibit the front portion of the disconnecting member from moving relative to the fluid transfer tip. The fluid transfer device is arranged such that upon application of a force to the rear portion of the disconnecting member, the disconnecting member deforms so that the engagement features are no longer in engagement with one another. This allows the front portion of the disconnecting member to move relative to the fluid transfer tip and subsequently release the hub from the friction fitting.
