In order to keep the final node stable, you have to alter the Constraint of ‘End Point’. A constraint to another object only controls its Position but not its Orientation nor Scale. Instead ‘End Point’ should be constrained to the World. Hence it is possible to select its degrees of freedom. By allowing no freedom at all (leave every Relax boxed unchecked) the object stays fixed!
Please allow me a remark. When I looked at Joshua’s model I was wondering how he defined the exact location of the Hinge joints which connect the nodes. Making a cross section of 2 nodes
I noticed not only that the volumes interfere (the small part is to large to fit into another node) but also that their design, the degree of the curvatures, do not take into account the possibility of rotation. No wonder “certain objects move clip through each other” like Joshua noticed. No limits can cure that.
I feel you need a different design, that at least allows some rotation between the links. Maybe something like this ? Snake Like 000.3dm (2.2 MB)

PS I used the circles in ‘Snake Like 000’ to define the exact position of the Hinges.
