Where, in Europe, I can buy online some ball joints to build a delta robot? Thanks.

So - you're incapable of typing into google "hobby shop radio-control europe"? That's where I would start. Then again, maybe someone here has a specific shop they could reccommend? You also didn't say how large of a delta robot (I am assumming hobby sized, though) - if it were to be something larger, I would say look into automobile parts (particularly steering and front-end suspension components).
RobotShop Europe has some lynxmotion ball/socket components - http://www.robotshop.com/eu/tubing-hubs-connectors.html
Thanks for you answer. Sure I can type in Google. But what i'm searching is experience. I think this is the goal of a forum. I'm searching someone that says: i built a delta robot and I used the ball joints, and I bought theme here. I'm speaking about a hobby size delta robot. However if you know a little the delta robots you know the robot size is not very important in order to choose the ball joints. One of the delta robot characteristics is the lightweight of the end effector

You didn't phrase it that way - the way you asked the question, implied you were looking for something (relatively) easily found with a google search.
While I know that a few people have built their own delta robot - the number seems like it is fairly small (compared to other robot platforms); I would tend to think this has less to do with the mechanics and more to do with the software control. You could probably do a bit of searching (hear and on google) and contact each of the hobbyists directly (PM or email).

I figured it was likely hobby sized - but for all I know you were planning on building a large 40 foot tall delta machine for next year's Burning Man; so questions about size and needs I felt were important factors...
I've used http://springfixlinkages.co.uk/ before for some balljoints. For smaller plastic balljoints I've investigated
http://www.igus.co.uk/ but didn't buy in the end (I went for ball bearings and Nd magnets instead taken from a "Geomag" magnetic construction kit.)
thanks Mark!
As an aside, for those looking for something slightly different, the type of joint with a bolt through the ball is called a rose joint.

Maybe I am misunderstanding your description - but it doesn't sound like one of these:
?
That's it exactly, rod end joint, heim joint, rose joint call it what you will but it's a ball joint of types.
