A latch assembly for connection of conduit, the assembly comprising a female portion and a male portion, wherein each of the female portion and the male portion have a shell and a connection device. The connection device of the female portion includes a connection assembly with a molded-in slot, a release button, and a raised rib or alternatively is a connection opening. The connection device of the male portion includes a cantilevered region with a ramped engagement feature or alternatively is a raised cantilevered release button. When connected the cantilevered region or button deflects to accommodate the female portion until the ramped engagement feature or button engages the molded-in slot or connection opening, thus releasing the deflection. Depressing the release button disengages the latch allowing separation of the assembly.

The assembly of claim 14, wherein the engagement feature of each cantilevered member is located on the tab near the free end of the tab. 16. The assembly of claim 10, wherein the engagement feature of each cantilevered member includes a sloped face facing a free end of the cantilevered member. 17. The assembly of claim 10, wherein the first and second leg portions of the slot of each cantilevered member extend away from the transverse portion toward a fixed end of the cantilevered member. 18. The assembly of claim 17, wherein the engagement feature of each cantilevered member is immediately adjacent to the transverse portion of the slot. 19. The assembly of claim 10, wherein the first and second leg portions of the slot of each cantilevered member extend away from the transverse portion toward a free end of the cantilevered member. 20. The assembly of claim 19, wherein the engagement feature of each cantilevered member is surrounded on three sides by the slot. 21. A connector assembly for coupling together first and second fluid conduits, the assembly comprising a first connector including a distal end for coupling with the first fluid conduit, a proximal end opposite the distal end, a fluid pathway between the distal and proximal ends, and a first housing extending about at least a portion of the fluid pathway and defining a release button; anda second connector including a distal end for coupling with the second fluid conduit, a proximal end opposite the distal end, a fluid pathway between the distal and proximate ends, and a second housing extending about at least a portion of the fluid pathway to define an inner cavity, wherein the second housing includes a cantilevered region having a free end located proximally of a fixed end;the cantilevered region has a pair of arms and an engagement feature;the pair of arms is defined at least partially by a slot within the cantilevered region that is open to the inner cavity; andthe engagement feature is located between at least a portion of the slot and the free end of the cantilevered region. 22.
