A method and apparatus for coupling with a spout to permit coupling of a valve sub-assembly housed in the apparatus with a slider valve housed in the spout. The apparatus includes a sleeve having at least two resilient finger members diverging from each other wherein each finger member has a flange engaging surface engageable with the flange portion of the spout. At least a portion of the sleeve is axially disposable about at least the flange portion of the spout, and the valve sub-assembly is slidable in the sleeve to couple with the slider valve in the spout when the sleeve is coupled to the spout. A collar is slidable over an outer surface of the sleeve for constricting the resilient finger members about the spout as the collar slides from an upper end of the sleeve and over the resilient finger members toward a lower end of the sleeve, and for releasing the constricted resilient finger members of the sleeve as the collar slides from the resilient finger members and toward the upper end of the sleeve. The flange engaging surface of the resilient finger members is engageable with the flange portion of the spout to couple the sleeve with the spout when the resilient finger members are constricted about the spout by the collar.
