ABSTRACT:
The connector assembly for double tubing includes a pair of interengageable coupling members that engage when latches on the respective coupling members are aligned in a predetermined nonlatching position. Locking of the coupling members together is accomplished by rotating one of the coupling members with respect to the other coupling member to interengage the respective latches of each coupling member. A latch section of one of the coupling members extends transversely of the coupling member body and a latch section of the other coupling member extends longitudinally of the coupling member body. A locking notch in one of the latch sections receives the other latch section to place the coupling members in a locked position when one of the coupling members is rotated to engage the latches. Further rotation of the coupling members unlatches the respective latch members to permit separation of the coupling members upon imposition of oppositely directed forces on each of the coupling members. Whether the coupling members are engaged in a locked or unlocked condition, fluid flow through the coupling members is maintained because engagement of the coupling members aligns the fluid flow tubes of each coupling member in leak-tight fashion.
