Question about the security locks for laptops, etc.

[markw10]

I want to purchase a Kensington lock which I'll use with my MacBook Pro and likely one also for my iMac and possibly Mac Mini.
It appears where they plug in in the side is simply plastic and they would be easy to rip away to steal a laptop but in general on Macs and other computers (I also have an Acer laptop I want to use them with) is there something that is steel reinforced inside to actually make it stronger? How easy is it to break off these locks?

They're not meant to be very sturdy... they can be torn out somewhat easily. The point is not so much to secure your laptop, but to leave a big hole if torn out which gives away that it's been stolen so thieves won't be able to resell them.

It's really not that easy to rip them out, it requires ripping off most of the side of the computer.
