Keeping praying hands locked together while moving

Hello!
I have created a pose for a nun which has praying hands.
Now I would like to be able to move the hands up and down in such a way that the fingers still keep crossed together.
Could somebody please tell me a keyword that I might google in order to keep them together?
I haven't found a way to do that yet.
Thank you.

DS has a facility to "lock" the rotation and or translation of body parts. However, in my experience "lock" is not a particularly accurate term in this case. Perhaps the term "restrict a bit" might be more accurate. Maybe there is deliberately some latitude for movement so as not to "break" the mesh. Personally, I would prefer at least the option of having a hard lock with a blurred edge, along with associated restriction of movement of attached body parts. I think this would be much closer to reality and indeed in your case allow your nun's shoulders to move at least a bit as she walked with hands fixed together.

mCasuals scripts can do that I would have a look at these:
