Beswick snap type quick disconnects QDC-101-I-DS (internal side) & QDC-101-E-DS-EB1 (external side), allow for quick tube connections and disconnections in a space saving design. This design incorporates an automatic shut-off mechanism in both the internal and external sides to prevent the fluid from escaping when disconnected.  Internal O-ring seals ensure a leak tight operation.  To connect, simply push the two halves together until they latch.  To disconnect, slide the knurled sleeve on the internal side back to release the internal end from the external end.
