that is most likely the vacuum line for your lock outs. the hubs are not always locked in with the auto hubs. the hubs use vacuum to pull in the a diaphram to lock the hubs when the selector switch is turned, on the dash. there are some truly manual hubs out there, but most seem to be the esof hubs, which have the back up manual locking feature.
