In reply to Basemetal: Also works for picks (squish flat and push to fit..)
If you put the cut piece of hose in a glass of boiling water for 30 seconds it softens it up and it can then be pushed / stretched/ moulded onto the pick easier, remove it, push it back on to the pick (almost, but not quite as far as the initial attempt) and then pour cold water over it to set it.
