The one on Quigley's website is the only one that exists, apparently. The photo is poor, she doesn't provide a link.

All the door jammers I could find are bars that you stick under the doorknob, except for this one http://www.911zone.com/shopdisplayproducts.asp?id=20&cat=Door+%26+Window+Jammers

And if that is indeed the one, Quigley should pay attention and get the name right. AND provide a link or source.
