A medical device has an interior for containment of fluids; an opening into the interior, an elastomeric wall comprising a fixedly placed, flexible barrier across the opening; and a retention wall positioned adjacent to a peripheral portion of the elastomeric wall. The retention wall defines a central opening and has a generally rigid retention zone surrounding the central opening, to engage and retain a connector tube which is advanced into the central opening to displace the elastomeric wall and to open a flow aperture through the elastomeric wall, for flow through the wall and connector tube. One of the retention zone and connector tube are made of a material of sufficient hardness that material of the other engaging member is deformed by engagement therewith, which increases the strength of retention between the retention wall and the connector tube.

That which is claimed is: 1. A medical device having an interior for containment of fluids; an opening into the interior; an elastomeric wall comprising a fixedly placed, flexible barrier across said opening; and a retention wall positioned adjacent to a peripheral portion of said elastomeric wall,
That which is claimed is: 1. A medical device having an interior for containment of fluids; an opening into the interior; an elastomeric wall comprising a fixedly placed, flexible barrier across said opening; and a retention wall positioned adjacent to a peripheral portion of said elastomeric wall, said retention wall defining a central opening, said retention wall having a generally rigid retention zone surrounding said central opening, to engage and retain a connector tube having a leading end which is advanced into said central opening to displace said elastomeric wall to weaken the resistance to flow of a closed perforation extending substantially through said elastomeric wall, said retention zone being sized to engage and hold said connector tube before said leading end completely penetrates said elastomeric wall, whereby the perforation of said elastomeric wall remains sealed, but can be opened for fluid flow by application of a low pressure differential in one direction to cause fluid flow through the perforation of said elastomeric wall, while said elastomeric wall exhibits a substantially higher resistance to said fluid flow under pressure when said elastomeric wall is not displaced by said connector tube. 2. The medical device of claim 1 in which one of said retention zone and connector tube is made of a material of sufficient hardness that material of the other of said retention zone and said engaged and retained connector tube is deformed by engagement therewith, to increase strength of retention between the retention wall and the connector tube. 3. The device of claim 2 in which said retention zone is ring shaped, and has an axial depth of no more than about 3 mm. 4. The device of claim 3 in which a plurality of spaces divides said retention zone into separate sections. 5. The device of claim 1 in which the material of the retention zone has a hardness of at least about Shore A 80. 6. The device of claim 1 in which said retention wall is spaced from the elastomeric wall. 7. The device of claim 1 in which said retention zone has an axial depth of no more than about 1 mm. 8. A medical device having an interior for containment of fluids; an opening into the interior; an elastomeric wall comprising a fixedly placed, flexible barrier across said opening; and a retention wall positioned adjacent to a peripheral portion of said elastomeric wall, said retention wall defining a central opening, said retention wall having a generally rigid retention zone surrounding said central opening, a connector tube engaged with and retained by said retention zone, said connector tube having a leading end which is advanced into said central opening to displace said elastomeric wall to weaken the resistance to flow of a closed perforation extending substantially through said elastomeric wall, said retention zone being sized to engage and hold said connector tube before said leading end completely penetrates said elastomeric wall, whereby the perforation of said elastomeric wall remains sealed, but can be opened for fluid flow by application of a low pressure differential in one direction to cause fluid flow through the perforation of said elastomeric wall, while said elastomeric wall exhibits a substantially higher resistance to said fluid flow under pressure when said elastomeric wall is not displaced by said connector tube. 9. The medical device of claim 8 in which one of said retention zone and connector tube is made of a material of sufficient hardness that material of the other of said retention zone and said engaged and retained connector tube is deformed by engagement therewith, to increase strength of retention between the retention wall and the connector tube. 10. The device of claim 9 in which said retention zone is ring-shaped, and has an axial depth of no more than about 3 mm. 11. The device of claim 10 in which a plurality of spaces divides the said retention zone into separate sections. 12. The device of claim 8 in which the material of the retention zone has a hardness of at least about Shore A80. 13. The device of claim 8 in which said elastomeric wall, when not displaced, can resist flow up to a pressure of about 1,500 mmHg, and when displaced by said connector tube said perforation can open in at least one direction at a pressure of at least about 80 mmHg. 14. The device of claim 8 in which said retention wall is spaced from the elastomeric wall. 15. The device of claim 8 in which said retention zone is ring-shaped, and has an axial depth of no more than about 3 mm. 16. The device of claim 15 in which a plurality of spaces divides said retention zone into separate sections. 17. The device of claim 15 in which the material of the retention zone has a hardness of at least about Shore A80. 18. The device of claim 17 in which said elastomeric wall, when not displaced, can resist flow up to a pressure of about 1,500 mmHg, and when displaced by said connector tube, said perforation can open in at least one direction at a pressure of at least about 80 mmHg. 19. The device of claim 18 in which said retention wall is spaced from the elastomeric wall. 20. The device of claim 8 in which said retention zone has an axial depth of no more than about 1 mm. 21. A medical device having an interior for containment of fluids; an opening into the interior; an elastomeric wall comprising a fixedly placed, flexible barrier across said opening; and a retention wall positioned adjacent to a peripheral portion of said elastomeric wall, said retention wall defining a central opening, said retention wall having a generally rigid retention zone surrounding said central opening, to engage and retain a connector tube having a leading end which is advanced into said central opening to displace said elastomeric wall to weaken the resistance to flow of a closed perforation extending substantially through said elastomeric wall, said retention zone being sized to engage and hold said connector tube before said leading end completely penetrates said elastomeric wall, whereby the perforation of said elastomeric wall remains sealed, but can be opened for fluid flow by application of a low pressure differential in one direction to cause fluid flow through the perforation of said elastomeric wall, while said elastomeric wall exhibits a substantially higher resistance to said fluid flow under pressure when said elastomeric wall is not displaced by said connector tube; in which said elastomeric wall, when not displaced, can resist flow up to a pressure of about 1,500 mmHg and, when displaced by said connector tube, said perforation can open in at least one direction at a pressure of at least 80 mmHg. 22. The device of claim 21 in which said retention zone has an axial depth of no more than about 1 mm.
