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.
