Little metal tubes in the straps?

[MNDZA]

What are the little metal tubes in the ends of the straps called? The part that you insert the little bar when attaching a new strap. I want to order a Ted Su strap and want to ask him if his straps come with these little tube things. My two Panerai straps that came with the watch have them built in. Are these hard to find and install if his straps don't have them?

if you don't get an answer,I would call them Panerai strap tubes,just say it's for a Panerai and I'm sure he will know what your asking for,and really no need to buy extra unless you really want too as they just push out.

they are usually called "tubes" by the 3rd party strap makers.
im sure they'd know what you are talking about.
most companies will include the tubes at no additional charges, but you may have to request them first.

They call them 24mm tubes, 26mm tubes, etc
