Well, if you've not actually installed one of these type connectors it is not as easy as you think to ascertain if you've made a good, solid, seal-proof connection. It is not fool proof. The clip will slide into place without the connector being fully seated. Yeah, maybe on the assembly line the installer gets used to the feel of a solid connection, but a open hose-end on a hose bib with a clamp gives a easy visual inspection that the fit is correct. I think it is just way over engineered and unnecessary. Just my pet peeve.
