摘要：
A fluid delivery apparatus includes a collet assembly having an upper and lower wall attached at a central portion of the collet. The central portion defines an inner step, and the lower wall includes circumferentially-spaced flexible tabs. The fluid delivery apparatus also includes a fluid distribution assembly coupled to the collet assembly. The fluid distribution assembly is positionable relative to the collet between a pre-use configuration and a pre-activated configuration. The fluid distribution assembly has a plenum that includes a sleeve component having an exterior ledge extending thereabout. A lower wall portion of the sleeve component includes protrusions corresponding to the flexible tabs of the collet. In the pre-use configuration the exterior ledge of the sleeve component is engaged with the inner step of the collet assembly, and each flexible tab engages a respective protrusion to provide a snap-fit between the fluid distribution assembly and the collet assembly.
