Abstract: Fluid connector assemblies that seal off fluid paths in the respective connectors are disclosed. When connectors of a fluid connector assembly are connected to each other, respective compressible members in the connectors are displaced, allowing downstream fluid passage through the fluid connector assembly. The connectors maintain a connection by a snap mechanism that provides a threshold retention force. When an external force greater than the threshold force is applied to the fluid connector assembly, the snap mechanism may no longer maintain the connectors together, causing the connectors to decouple from each other. However, each of the compressible members can return to their respective original positions and shapes to seal off respective fluid paths in the connectors, thus preventing further downstream and upstream flow through the fluid connector assembly and limiting or preventing fluid loss.
