I broke my washer nozzle right where the line plugs in and thought of doing this but used epoxy instead of super glue because I was out of it. Was a pain to get an initial hold but 1 hour later I coated it in red silicone sealant.
We also used the same red silicone sealant where we didn't thought it would really last or even stick: plugin a 2 inches hole left in an intake pipe with an oil jug cap, and sealing an hole left in a coolant overflow tank with a screw... Inserted from the outside!
