a first attachment body forming an open curve configured to conform with the inner structure, wherein a radially outermost surface of the first attachment body forms a curved surface;
a second attachment body forming an open curve configured to conform with the inner structure, wherein a radially outermost surface of the second attachment body forms a curved surface;
the first attachment body attachable with the second attachment body to define a central aperture extending along a longitudinal axis between the open curve of the first attachment body and the open curve of the second attachment body, wherein an exterior portion of the inner structure is secured within the central aperture;
a top of the first attachment body;
a floor of the first attachment body located vertically below the top;
a hollow spacing located axially between the top and the floor of the first attachment body;
an interior wall formed by securing the first attachment body with the second attachment body, the interior wall defining a diameter of the central aperture;
a first retention finger extending radially inward from the interior wall, the first retention finger decreasing the diameter of the central aperture at the first retention finger; and
a second retention finger extending radially inward from the interior wall, the second retention finger decreasing the diameter of the central aperture at the second retention finger, the second retention finger located vertically below the first retention finger; and
wherein the second retention finger is located vertically below the floor;
wherein an exterior surface at the second retention finger is located radially inward from the exterior surface at the floor.
