ABSTRACT:
A quick connect coupling includes male and female elements of which one includes a closure valve that is spaced inwardly from an open end of the one element and that is opened by engagement of the other element after a portion of the other element passes through an annular opening in the one element. To prevent accidental opening of the valve, a ratio of a radial width of the annular opening and a depth of the annular opening between the valve and an entrance into the annular opening is less that 1.
