Using the clip utility with special characters

I'm trying to copy text to the clipboard from the command line. If I try something simple like:

ECHO test | CLIP

it works fine and puts the word test in the clipboard. My problem is that I have a special character (specifically an ampersand) in the text I want to copy and it makes the clip utility choke:

ECHO http://wwwapps.ups.com/WebTracking/track?track=yes&trackNums=1ZV300F20358346597 | CLIP

If I try the same text without the ampersand, it works fine so I know it's the ampersand that is causing the problem.

I tried using quotation marks like this:

ECHO "http://wwwapps.ups.com/WebTracking/track?track=yes&trackNums=1ZV300F20358346597" | CLIP

That gets rid of the error but the quotation marks get copied to the clipboard, too.

Any ideas?

Thanks in advance.
