Mini pump - can I use any hose extension?

Hi I've got a Topeak Pocket Rocket, and wondered if a standard hose connector will fit onto it? So that I avoid damaging the presta valve when pumping.
Would something like this work.. http://www.evanscycles.com/products/wel ... e-ec038109 ?

Why ? because you'd never hold it in the nozzle of the pump itself, the pressure would just blow it out.
Wish I spent vouchers on something different and got a lezyne with hose instead of topeak
