fluid pressure as shown in fig6 and mechanically separating the coupling members 14 and 16 it should be appreciated that the instant invention results in a simple and effective apparatus for connecting low pressure fluids in a quick connect and quick disconnect coupling the coupling is essentially incapable of separation after the flexible means 44 has been radially expanded into the female radially enlarged portion 26 by the application of fluid pressure the male and female couplings 14 and 16 cannot be disconnected or separated as long as fluid pressure is present within the fluid carrying members 11 and 12 only upon termination of the fluid pressure can the male and female coupling members 14 and 16 be separated by mechanical means this safety feature is of substantial importance when used with corrosive or dangerous fluids fig7 10 are side sectional views of a second embodiment of a fluid coupling 110 comprising of male and female coupling members 114 and 116 in a series illustrating the interconnection between the male and female coupling members 114 and 116 upon application of fluid pressure this second fluid coupling 110 is substantially similar to the coupling 10 and similar parts will be labeled with similar reference indicia the female coupling member 116 includes a first and a second conduit portion 122 and 124 having first and.
