Claim Text:
1. An apparatus comprising: a conduit housing including a tube segment; one or more pump interlock elements adapted to facilitate detachable engagement of the housing with a peristaltic pump; an anti-free-flow mechanism having a first default state which obstructs flow through the tube segment when the housing is detached from the pump and a second mechanically latched override state which allows fluid to flow through the tube segment when the housing is detached; and a third engaged default state wherein said anti-free flow mechanism is brought into the third state when the housing is attached to the pump, from (a) the first default state if the anti-free-flow mechanism is in the first default state when the housing is detached from the pump and from (b) the second mechanically latched override state if the anti-free-flow mechanism is in the second mechanically latched override state when the housing is detached from the pump.
