ABSTRACT:
A quick-connect fluid coupling for fluid conduits includes first and second identical inter-fitting bodies (10, 10'). Each of said bodies includes barrel portions (14) and sleeve portions (16). The sleeve portions include barrel accepting recesses (34). Each body portion also has a forward projection (48) including an angled ramp (50) and a step (52) and an opposed U-shaped latch (54). The body also has tubing accepting bores (26, 42) which accept ends of fluid conduit tubes. First and second fluid passages (30,46) extend through the body to the barrel portion and barrel accepting recess respectively. When the bodies are joined in opposed inter-fitting relations, the barrel portions on the first body are accepted into the barrel accepting recesses on the second body and vice versa. The step on the forward projection on the first body catches in the U-shaped latch on the second body and vice versa to hold the bodies together. The bodies forming the coupling are readily separable by depressing the forward projections and pulling the bodies apart.
