ABSTRACT:
There is provided a quick-action push-in connector for fluid-carrying tubing. The connector comprises an outer member having fluid passage means and an inner member at least partly accommodatable in the outer member. The inner member has a substantially central passage adapted to admit the tubing and to allow the same to communicate with the fluid passage means and is provided with at least one inwardly directed gripping protrusion adapted to engage the tubing. At least at the protrusion, the inside diameter of the inner member is elastically reducible by interaction of the inner member with at least a portion of the outer member, and elastically expandable by application of a spreading force, and is in the free, unreduced state, smaller than the outside diameter of the tubing and adapted to undergo an initial expansion when the tubing is pushed in. An attempt to pull out the tubing once pushed in will initiate the interaction, whereby the protrusion exerts a gripping effort on the tubing, preventing the withdrawal thereof.
