I just recently got myself one of those "hair-clip" queen catchers. I now consider it a must-have and load it into my shirt pocket whenever I am getting ready to work my bees. It is a very helpful tool for queen management. A few weeks ago I even used mine to catch a virgin queen -- I left her in the cage and set it on the entrance where it was quickly covered in a thick layer of workers. Once I had finished and was closing up the hive I took the cage in hand and brushed some of the workers off the cage so I could see the queen prior to releasing her into the top of the hive. There she was, then as I moved the cage down near the tops of the frames, she simply slipped out of the cage and made her own way down into the hive, even before I had begun to open it for her. I guess that makes her a temporarily willing captive. Her own workers were probably helpful in keeping her in the catcher cage while I worked the hive.
