R52 Coolant Change - Hose Clips?

Having changed the coolant, now got a small leak from the bottom radiator hose. When I changed the coolant I re-used the original metal retaining clip (why is not a jubilee clip?). Are these one time only use?
Can I replace the metal clip with a jubilee (bit worried if I over tighten it will crack the plastic radiator housing tho).
To add to woes, my local spares shop just looked confused when I asked about ordering new hose clips.(offered jubilees instead).

You can replace the clips with jubilee clips
just dont overtighten them

Never had a problem re-using the original clips. Sounds like the hose isn't seated correctly or the hose is damaged.

Cheers for the replies. Have had the hose off twice, reseating it but still a small leak. The hose looks fine.
Will try the jubilee, but not do my usual "tighten it one more time just to make sure".
