It looks to me like the tube that comes off the radiator that the hose connects to broke off. I am also trying to figure out what the deal is with the brown wire connected to the clamp.

I am no Volvo expert, but, I suspect your radiator is toast and you need a new one, how long have you had this car and was the brown wire always there? Seems like it was a problem before and a band aid was applied.
