Not sure of the actual name, but they're like wire nuts but crimped instead of twist. I don't think there's a non-destructive way to undo them but you may be able to rip the wires out and use a regular wire nut to splice them back. If not, try cutting them as far inside as you can and replacing with another crimp connector or use a screw type wire nut.
