Name of this crimp connector?
This kind of crimp splice connection is popular in appliances, as it requires no soldering and can be  used at relatively high temperatures. It comes off a roll of such connectors or a roll of strip brass, in which case it can be called a band splice. 

I have emulated this with ferrules and a collet hand crimping tool in order to fix our prized sandwich maker by replacing the internal thermal fuse. They called it too close on the temperature rating and it was already the highest temperature easily available (240°C) so I moved it a bit to make it run slightly cooler.
