A connector for facilitating fluid transfer includes first fitting, a second fitting, a rigid conduit, a first retaining connector, and a second retaining connector. The rigid conduit includes a flexible tube surrounded by a deformable sleeve. The rigid conduit is connected on a first end to the first fitting and on a second end to the second fitting. The first retaining connector connects the first fitting to the rigid conduit and the second retaining connector connects the second fitting to the rigid conduit. A lumen extends through the rigid conduit and is capable of being sealed. The rigid conduit and the flexible tube are capable of being severed while maintaining the seal of the lumen to separate the first fitting from the second fitting. The connections of the first fitting and the second fitting to the rigid conduit are capable of withstanding at least 1 bar of pressure without leaking.

A failsafe system for a medical fluid procedure, comprising a medical fluid processing apparatus comprising a sealer and a programmable controller driven by software, wherein the programmable controller is programmed to recognize a failure event from input from hardware components of the medical fluid processing apparatus. The system also comprises a disposable fluid circuit configured to associate with the medical fluid processing apparatus and comprising a tubing segment configured to fit within the sealer. The programmable controller is configured to seal the tubing segment by activating the sealer surrounding the tubing segment in response to an occurrence of the failure event.

A clip device for occluding two fluid lines and forming a fluid connection includes one of the fluid lines, the clip device including: a first clip segment including a fastener for engaging to a first fluid line, a first pinch valve for occluding the first fluid line and a coupling for connecting to the first fluid line; a second clip segment including a second pinch valve for occluding the second fluid line; and a bypass fluid line connectable or connected to the coupling. The second clip segment may also include a fastener for securing to the second fluid line. The first clip segment and/or the second clip segment may include a proximal opening and a distal opening through which the tubing passes. The proximal opening and the distal opening may be disposed on opposing sides of the segment.
