washer reservoir mystery

[Finisterre]

there is an eight inch long, thin 4mm tube and a colleted nozzle in clearish plastic knocking about in our washer reservoir.

Does anyone know where they are supposed to be and what they are for?

Thanks for reading

I wondered that.

Hopefully someone will have had a bit ofa nose and know the answer.
