The spark plug cap has a self tapping screw in it.
The HT lead consists of a small bunch of wires, which over time get pushed into the outer plastic casing of the lead.
If you snip 5-10mm off the ends of each lead you can then carefully screw the cap back in until it stops and feels firm for a fresh connection.
It's quite important that the connection is good and solid otherwise it can cause running issues, especially in bad weather.
Also another option, which a lot of us have done because they are so dirt cheap, is to replace the caps for under a tenner with NGK ones, which work absolutely fine.
Last time i checked original replacements were at least 20 times more expensive. :eek
