They need to replace that clip with a saddle block style clamp design. Here is a sketch I made up to show the concept:

My local dealer told me they would replace it free under the Platinum Maintenance program the car was covered under that was purchased when the car was new. I have an appointment to let them fix it but in the meantime I have zip tied it up out of the way so it doesn't rub. It might be about as good as using the poorly designed clip. I will probably go back in and put in zip tie around the new clip and lines in case it breaks again or to help prevent it from breaking again.
Here is a link showing before and after pictures and a video of how I did it after it was done. On mine only the right side of the clip was broken and I took the metal clip that is further back by the suspension off and pulled some of the slack out of the line and reattached it about an inch or so further up the line and then zip tied it around the back side of the heat shield bolt.
