3ds max: Rigging a hose

I have a character with a tank on his back and a hose that leads from the tank to his hand, and he's going to be moving it around spraying things, how do i rig the hose to bend and move between the tank and the characters hand

just make the hose a rope type object in a animate using physics
The tank and hand attachpoints should be the constraints of both hose ends

Wouldn't it wobble about a bit too much?

Is there any way to attach objects to an existing rigged character?
Like say adding the tanks on the characters back after the character is rigged? cuz i am lookin at attacking the tanks to the mesh and having to re-rig this model
Id prefer to not have to re-do it all

Just group it i guess?
That should work
Or link it

I have to add a bone or two in i would think
Or maybe not...
