Abstract
An improved docking assembly for faucets having a pull-down sprayhead extendable from a spout. The docking assembly generally comprises a receptacle fitted into the spout which is formed with chamfered interior walls. A spring-loaded flexible collet is contained within the receptacle with a degree of sliding freedom for spring-biased travel along the chamfered interior walls of the receptacle, from a first position that allows generous radial expansion of the collet to a second position in which radial expansion is restricted. A quick-connect fitting attached to the pull-down sprayhead moves the collet into its first position allowing radial expansion of the collet. Removal of the quick-connect fitting moves the collet to its second position which restricts radial expansion, inhibiting said removal. Consequently, the pulldown sprayhead may be docked to the spout with considerably less insertion force than the opposite removal force needed to undock the pulldown sprayhead from the spout.
