WTF is this part called and where can I get a replacement?

[chicane]

This part holds the seat wiring harness onto the seat rail underneath both the PS and DS seats. My driver side "harness holder" is broken and I need a replacement.

I went to the bone yard but all the standard E46's do not have this part. The harness connector clips directly unto the bottom rail. There is no Part # on the part. Any assist is appreciated.

Looks like part # 61131381951
