Is it safe to close the CPU lock on a motherboard if there's no processor in the socket?

So I was one day doing some PC maintenance and I closed the CPU socket of the motherboard without the cover on the lock and without the CPU in the socket. Will doing this bend the pins? By black cover, I mean that thing that's on the top of the CPU lock(I think lock is the correct term?) of a brand new mobo. This is what I mean by I closed the socket without the black cover or CPU inside the socket:

I can't imagine it would, storing it like that will expose the pins to dust etc, but for short-term maintenance, it ought not be an issue, as longs as nothing cracked or anything.

It should be fine.
