1. A QUICK CONNECT-DISCONNECT COUPLING FOR FLUID CONDUITS COMPRISING:

A TUBULAR COUPLER HAVING AN ANNULAR SEATING SURFACE FORMED AROUND THE INTERIOR WALL ADJACENT ONE END AND RADIALLY OUTWARDLY EXTENDING ABUTMENT MEANS SECURED TO THE EXTERIOR WALL ADJACENT THE OTHER END;

A TUBULAR ADAPTER RECEIVABLE IN THE COUPLER AT THE END ADJACENT THE ABUTMENT MEANS AND HAVING AN ANNULAR SEATING SURFACE FORMED THEREON FOR MATING WITH THE SEATING SURFACE FORMED IN THE TUBULAR COUPLER;

AN ANNULAR CONCAVE GROOVE IN THE EXTERIOR WALL OF THE ADAPTER;

A SLEEVE BRACKET SLIDABLY DISPOSED AROUND THE COUPLER HAVING ONE END THEREOF ADJACENT THE ABUTMENT MEANS;

LEVER OPERATED CAM MEANS PIVOTALLY CONNECTED TO THE SLEEVE BRACKET FOR COACTION WITH THE ANNULAR CONCAVE GROOVE;

APERTURE MEANS IN THE TUBULAR COUPLER FOR PASSING THE CAM MEANS THROUGH THE COUPLER FOR ENGAGEMENT WITH THE ANNULAR CONCAVE GROOVE;

RESILIENT MEANS DISPOSED BETWEEN SAID ABUTMENT MEANS AND THE END OF THE SLEEVE BRACKET ADJACENT THERETO FOR TRANSMITTING A FORCE EXERTED ON THE SLEEVE BRACKET TO THE TUBULAR COUPLING, WHEREBY UPON INSERTION OF THE ADAPTER INTO THE COUPLER AND PIVOTATION OF THE LEVER OPERATED CAM MEANS, THE SEATING SURFACES WILL BE FIRMLY PRESSED TOGETHER BY FORCE TRANSMITTED FROM A SIDE OF THE ANNULAR GROOVE IN THE ADAPTER THROUGH THE CAM MEANS TO THE SLEEVE BRACKET, AND FROM THE SLEEVE BRACKET THROUGH THE SPRING MEANS TO THE ANNULAR FLANGE AROUND THE EXTERIOR WALL OF THE COUPLER.
