Transmission hose connector to oil cooler plastic clip ring lost - 17221711465

Anyone know if these plastic 'ring-clips' can be easily sourced? - or am I going to a junkyard this weekend?
- I lost one while removing the line to do a transmission flush.

Thanks!

They age quite badly, you can only buy the whole lines, they are expensive ($150-$250 depending which one).
I have just replaced both of them over the weekend, easy job.
