I am helping a family member with some things around the hose and discovered that their kitchen faucet is leaking from the base of the sprayer hose while it is being used.
I would like to disconnect the hose so I can examine and replace the parts as needed. However, I can't figure out how to disconnect the hose from the base of the spray nozzle. If I grip the hose in one hand, and turn the nozzle with the other hand, the nozzle rotates freely. Thus it does not appear to be a threaded connection.
I'm not sure of the manufacturer and model so my attempts at research have thus far failed. Here's a picture of the nozzle where the hose connects to its base:
