It's possible to approximate this by creating a bunch of short "pieces" of hose that are connected to each other via a joint. If you want only 2d motion then use a pin joint. Otherwise you can use 6DOF joint... You then assign some sort of stiffness to the rotational axes of these joints (using a spring). You'll need to run a static (in Mechanism Dynamics Option) analysis first to make sue everything goes to the correct initial position...
Here's an old example image showing the discretized hose, the pin joints etc... Have fun!
