A system for controlling flow of a fluid in a tube with a controlling device includes a pinch clamp. The pinch clamp has a first leg, a second leg, a connecting region there between, a pinching region, and a first part of a quick release connector. The first leg and the second leg are both connected to the connecting region. Whether the pinching region is in an open position or in a closed position is determined by spacing between the first leg and the second leg. The first leg includes the first part of the quick release connector. The first part of the quick release connector includes an element for quickly mounting the pinch clamp to the controlling device and for quickly dismounting the pinch clamp from the controlling device.
