Three rings (planar circles) are "linked" together, but you'll notice that none is directly linked with another.

• The red ring is "behind" the yellow.
• The yellow ring is "behind" the blue.
• The blue ring is "behind" the red.

Still, while none is intertwined with another, it is impossible to pull them apart.

Is this a paradox?

Can this really be built?

Given the frontal view only I belive the image can be created if you allow the top-down view to be highly irregular.
