Yes, they're stops on an L-shaped bracket which allows them to slide around a corner. You install them on the upper window at whatever height you want. When the stops are on the front face of the window, it prevents the lower window from sliding past it. When you turn the stops to the inner side, they no longer block the window.

Wow, that's a ridiculously long URl. Anyway, we installed them in all our first floor windows years ago, when we first moved in. Technically we should have them on some of the second floor windows as well, since there are porches.
For what it's worth there's a way of hiding urls but making it still visible - so you could have your link above like this: security item. The way it works is you put square brackets around the title [security item], then without a space between, put the URL in parentheses (like these).
The code only activates, I believe, if you've got the square brackets and parentheses unseparated.
