ABS sensor connections

[stu sim]

ABS warning and service light has come on , i've discovered that its because the ring on the front wheel baring has corroded so badly that the sensor cable has came away , at the moment its only one side but have been told the other side is only just hanging in their !!!!! the problem i've got is it comes as part of the wheel baring kit sold from Renault at just under 40 quid a side . im just wondering if anyone has experienced this same problem and found a supplier of the baring ring clip part im talking about as i dont need 2 new front barings and dont want to go to the scrapys either because theirs no guarantee im going to get the part any better than the ones ive got THANKS !!!! hope someone can help.
