What you need is a faucet to hose adapter. Danco makes one.
This site mentions the hose:
I took note of the model number 36115B and searched around and found this place that sells it:
But if you live in San Francisco, you can go to the hardware store on Mission Street near duboce, just past the overpass on 1695 Mission Stret, Discount Builders Supply (I think it's Ace Hardware now) or any number of hardware stores elsewhere. When I lived in The City, Discount Builders was my place to go for paint, plumbing, and apartment upgrading supplies. My favorite store, always the lowest prices.
According to the above site the adaptors are available at Home Depot so you can try driving over the bridge to Emeryville and checking out the Home Depot store over there (it's out over by Ikea, [url=https://maps.google.com/maps?sourceid=navclient&ie=UTF-8&rls=GGLD,GGLD:2004-51,GGLD:en&um=1&q=home+depot&near=Emeryville,+CA&fb=1&cid=0,0,7205659174230057078&sa=X&oi=local_result&resnum=1&ct=image]Google map it[/url]).
I'm glad you asked this question because this is something I need, too.
