Abstract
Aperture retention arms can extend outwardly away from an aperture shaft. An insertion end can be positioned below the aperture retention arms and can have an overall conical shape. The insertion end can include an opening having a closed interior terminal end separating a portion of a first lateral half of the insertion end and leaving another portion of the first lateral half as a connecting bridge below one of the aperture retention arms. The opening can include a channel extending from the closed interior terminal end to an open exterior terminal end to separate a second lateral half of the insertion end below another of the aperture retention arms. The insertion end below the open exterior terminal end of the channel can extend laterally outwardly beyond a straight exterior line defined by laterally outermost points of an outer longitudinal side of the second aperture retention arm.
