Rear end accident - tow hitch plastic parts damaged

[JGEM]

On the way to work this morning my wife was stopped at the lights and a VW Golf ran into the back of her. Not high speed luckily, my wife is OK, just a minor soreness in her neck from the jolt. The XC60 tow hitch socket took a heavy blow and punched a square hole through the bumper of the VW

I've crawled under the XC60 and had a good look around and there is no sign of bending or deformation of the metalwork where the tow hitch is mounted. It's a dealer fitted Volvo branded tow hitch. What is damaged however are the plastic fittings at the end of the tow hitch - I've attached a photo of the 2 separate bits and I was wondering if anyone knows what the Volvo part numbers are for these 2 bits (assuming they are available separately)

The XC60 is off to a panel shop on Wednesday to have them look it over and confirm that there is no other damage.
