Unable to remove PETG tubing from Manifold

I am absolutely unable to remove the

PETG tubing from the SparkX manifold. I

tried a tool to depress the black ring. I

tried a lot of force . Nothing worked. This

needs to be fixed. I did purchase some

PETG tubing couplers from Amazon.

This works well to split another piece

of tubing onto the retained tubing.
