Lower region of a cylindrical nozzle stem is longitudinally slotted to provide flexible tines and the tines have outwardly projecting lands at their distal ends. The flexibility of the tines permits the nozzle stem to be force filled into and through a ribbed region of a surrounding retainer. Further, the flexible tines permit a cylindrical metal weight, and a weight cover to be slipped over the lower end of the nozzle stem to be held in place by the lands on the tines. No separate fasteners nor adhesives are required to hold the assembly together.
