ARRGH sump pipe popped off!

Hmm i had clipped my sump pipe tightly (so i thought) onto the return pump,
so when i went into work to show my other half my lovely tank i came in to
find a lovely shimmering on the floor of salt crystals and an almost empty
sump!
Luckily for me the water flow in the main tank wasn't too badly affected as
the 2 power heads were still circulating the water well.
Just out of interest would it be ok as a temporary measure to use a
stainless jubilee clip on the pipe until i can find a more robust plastic
clip to replace it, i know it will probably rust quite fast but would it
affect the fish/inverts?
