Just having a clearout in the garage, and came accross these two items, one is reusable and the other was a one time use. This one is why I remove all the Volvo locking wheel nuts on each new Volvo that comes into my posession and replace them with non locking nuts. This one is a vital special tool that allows me to change headlight lamps without messing around and removing too much. Its actually a blue spade connector with a pop rivet (unused) crimped in where the wire would normally go and insulation tape wrapped around the while lot. With the help of a torch, mirror and magnet, I did the last lamp change in less than 15mins. FYI I have opened up the spade connector so it is an easy slide off, that way the lamp remains in place when you pull the space connector off.
