Abstract A MULTIPLE HARNESS STRAP QUICK RELEASE BUCKLE FOR FIRST RELEASING THE SHOULDER STRAPS AND THEN THE RESTRAINT BELT AROUND THE WAIST OF THE USER. THIS BUCKLE COMPRISES PAIRS OF PIVOTED, SPRING-BIASED LOCKING DOGS HAVING CAM PORTIONS WHICH ARE OPERATED BY STRAP INSERTIONS TO MOVE THE DOGS TO LOCKED POSITION. AS THE DOGS GRAP THE STRAP INSERTIONS, SPRING ACTUATED SADDLES MOVE DOWN BEHIND THE DOG TO PREVENT THEM FROM UNLOCKING. TO MOVE THE DOGS TO UNLOCKED POSITION, A FIRST UNLOCKING DEVICE MUST BE OPERATED PRIOR TO THE OPERATION OF A SECOND UNLOCKING DEVICE FOR RELEASING THE LOCKING DOGS WHICH THEN ARE SEQUENTIALLY UNLOCKED.
