A self-tightening clip having a planar member (16) and at least one retention member (18) attached to the planar member. The planar member (16) includes an inner perimeter, an outer perimeter, and defines a central axis (24). The least one retention member (18) including a planar leg portion (30) and a planar hook portion (32). The leg portion (30) extends from the inner perimeter in a first direction along the central axis (24). The hook portion (32) projects from the leg portion (30) toward the central axis (24) in a second direction, which is opposite the first direction along the central axis. The hook portion (32) is acute to the central axis (24) and has a free end located on an imaginary perimeter concentric to the inner perimeter of the planar member (16). The central axis (24) and a plane passing though the hook portion (32) of the at least one retention member (18) form an angle in the range of approximately 20 DEG -30 DEG . <IMAGE>
