Kitchen sprayer hose leak. Not sure how to remove clip or even reach it.

Hose has pinholes in multiple places. Can barely reach this clip with one hand to disconnect but also don't know how to remove it. I believe the part number is MODEL#: RP44647. Does anyway know how to remove it? Sink has divider in middle which makes it difficult to reach, can only get one hand up there. Thanks for your help.
