I took a look at these, and the clip should work. However, I found a datasheet for that programmer [1], and there does not seem to be any pins which can act as a 3.3V supply, which is required. There might be ways around that [2], but I don't know for sure if that method will work on the X220. So that programmer may not be ideal. > It seems the connection of the jumper wire, that's going to be connected with > the programmer, needs to be female (socket) because the programmer seems to > have a male connection (pins) with the pin header already soldered on.

Reading the description of that clip, it looks like it ships with those extra boards as well as the wires. Based on the connections on the clip and the boards, the wires are female to female, but the connectors on the ends of the wires appear to be connected together in 2 blocks of 4. They should be separate in order to connect each wire to the correct pin on the programmer. So if you get that clip, you would still need to get separate female to female jumper wires. For the programmer that you linked, a USB extension cable would likely be needed, as the way USB ports are typically oriented on laptops means that the pins on the programmer would face the table, making it difficult to connect anything to it. However, that may not be needed for other programmers depending on the way the pins are soldered on.
