ABSTRACT:
A quick-connect coupling for connecting and hydraulically sealing two tubes that carry fluid has a spring member fixed to the end of one tube and a latch member having inclined surfaces formed at the end of the second tube. The second tube is fitted over the first tube and is inserted within the spring element allowing the element to be resiliently deflected on the inclined surfaces as the second tube is moved axially toward the first tube during assembly. The spring member applies a force to the second inclined surface that tends to force the second tube toward the first tube and the spring member into contact with a locking surface on the latch member.
