A coupling between a reinforcing rib component and an underbelly component of a vehicle is provided. The coupling comprises a tooth projecting from a first of the components through a second of the components, an aperture formed in the second s component and receiving therethrough the tooth, and one or more coupling elements attached to the tooth and bearing against the second component. The tooth urges the coupling elements toward the second component, thereby increasing the contact pressure between the components.
