Thank you for your inquiry! The plastic connections tab below on the spout nipple, below the sink, of the Delta Lorain Kitchen 21716LF faucet should not be removed. To connect the Quick Connect Sprayer assembly to your Lorain Kitchen faucet 21716LF model, you would push the end of the hose assembly up onto the nipple of the faucet. It would snap onto the blocked/tabs, above the two orings on the nipple. I have included below the Installation instructions and diagram, pg 2 module 4.
