It's actually pretty easy.
I used a pair of foreceps (pliers, salad-tongs, whatever you have. Careful, it's hot!) and dipped just the end in a 1/4" of boiling water for 45 seconds. Then removed the cap with my normal "whatever is on hand" - a multimeter probe in this case, but whatever you normally use will work too.
The point is that a quick dip in the "spa" is enough to soften the glue and make removal (careful, did I mention _hot_?) of the end-cap possible without destroying or even deforming it.
