Heater hose quick connect fitting!

I had an antifreeze leak that was coming from
where quick connect pushes into the bottom
heater hose! After I got the quick connect off and
hose cleaned out ,I just pushed the hose all the
over the nipple on the pipe and used regular clamp
to tighten! It runs fine with no leaks ,my question to
you is it OK to run without quick connect fitting or
is that just to help in repairs quicker .
