The invention relates to a connector which has an inner displacement member. The flow is stopped by the connector, i.e. the connector is impervious, in a first position. In a second position of the displacement member, with a stop defining the position, flow apertures are released which release the flow into the flow carrying line.

1. A connector having hose connections at a proximal end and a distal end, said connector comprising: a generally cylindrical body surrounding a hollow lumen that allows flow therethrough to an outlet aperture, said lumen including a tapered region; an inner displacement member supported within said lumen and having a flow aperture therein, an outer end portion of said displacement member opposite said outlet aperture for being pushed to move said displacement member axially from a first position in which fluid is prevented from flowing through said aperture by said tapered region, to a second position in which said flow aperture is irreversibly opened for fluid flow therethrough, said connector being free of any means for moving said displacement member back from said second position to said first position. 2. The connector in accordance with claim 1, wherein said displacement member includes a stop that defines said second position, said stop contacting said tapered region to prevent further axial movement upon displacement of said displacement member from said first position to said second position. 3. The connector in accordance with claim 1, wherein said connector is made of plastic and is a disposable article. 4. The connector in accordance with claim 3, wherein said displacement member is made of silicone rubber. 5. The connector in accordance with claim 1, wherein said displacement member is displaceable from said first position to said second position exactly one time. 6. A connector having hose connections at a proximal end and a distal end thereof for connection to a hose system, said connector comprising: a housing surrounding a hollow lumen that allows flow therethrough, said lumen including a tapered region; an inner displacement member supported within said lumen and having a stop and a flow aperture therein, said displacement member starting in a first position in which said tapered region prevents fluid from flowing through said aperture and, simultaneously with said connector being connected to said hose system, said displacement member being axially and irreversibly moved through contact with a corresponding component of said hose system to a second position in which said flow aperture is unobstructed by said tapered region and thereby opened for fluid flow through said aperture, said stop contacting said tapered region to prevent further axial movement upon displacement of said displacement member from said first position to said second position, said connector being free of any means for returning said displacement member to said first position such that said displacement member is displaceable from said first position to said second position only one time. 7. The connector in accordance with claim 6, wherein said connector is made of plastic and, being designed for a single use, is a disposable article. 8. The connector in accordance with claim 7, wherein said displacement member is made of silicone rubber.
