see pic (slightly out of focus - sorry)but you can just make it out stuck down the end of the lead

i can then remove the plug from the block fine, but i am left with the small metal end bit that is normally screwed onto the top end of the plug, wedged in the end of the lead with no way of getting it out!
any suggestions on how to remove it from the lead?
the small screw threads at the end of the plugs have stripped and won't grip the bit wedged in the lead
Dont really want to have to spend £50+ on new leads if i can help it!
any sugestions appreciated
