A closure ring section, that is connected to the transfer line, is provided for fitting onto a retaining ring of the bulk head female connector. The closure ring section includes a cylindrical shaft that is arranged axially therein that includes a forward end for engaging and compressing the resilient sleeve when the coupling ring is fitted onto the retaining ring, the resilient sleeve when compressed to bow outward around its mid portion, lifting the sleeve interior surface off from and opening the side ports, providing a passage from the container to the transfer line.
