2d ragdoll joint connection.

Im trying to figure out how to link the joints of a 2d ragdoll like this ragdoll

should i use joints, and if so which joint would be best for making sort of a pin connection where the 2d planes can swivel around.

-edit: i dont have bones in my 2d doll. iv been trying to get away with not rigging my 2d ragdoll. but i dont think i can. so im gonna go back in blender and give it some bones
