Abstract:
Apparatus for locking a fluid fitting of a flexible bag in a port, the fluid fitting comprising:tubing connected to and projecting from the bag, the tubing having a first flange adjacent the bag and a second flange spaced axially from the first flange for forming an annular locking area between the first and second flanges, the annular locking area having a polygonal perimeter; a port formed in a wall of a fluid retaining container; a flexible diaphragm having a periphery which has a diameter greater than the port, a polygonal opening complementary to the annular locking area having radial dimensions smaller than the radial dimension of the second flange, and two or more cuts extending radially from the opening for forming two or more radial flaps, so that when the fitting's second flange is pressed forcibly against the flaps, the flaps flexibly deflect out of the plane of the diaphragm so as to permit passage of the second flange therethrough, the flaps then snapping back flexibly to engage the fitting's polygonal locking area to the diaphragm's polygonal opening; and a ring for securing the diaphragm's periphery to the wall about the port.
