what set contains this part.

I was looking at some of the chima sets today the hero factory style ones I think. and I noticed a figure which had what looked like those little grey T shaped pieces that were used in hydraxon 8923 set but the base with a cross axle connected to the bar were the fingers or claws could clip on to.

Xan some someone post me the set nuber with that part and what its offical name is when trying to bricklink or ebay a few?

You're referring to the pneumatic connector piece, which was used for all of the monsters in the second wave of Invasion From Below (2014) and in Rocka's Stealth Machine from the first half of 2014 as well.

In Bricklink, go to the Catalog tab and type in the set number, 8923. When the window appears, click on the (Inv) that appears before the thumbnail for Hydraxon. You should then be able to scroll down through the inventory till you see your part.

LockdownTF was referring to a similar piece to the one that appeared in 8923, so just doing that wouldn't work, although you may be able to find the correct piece by looking at other parts in the same category.

You're refering to part number 99021.

There you can find in which colours does the piece exist, as well as in which sets it appears.
