Injection Mold for a Retention Device

Abstract

Embodiments of a retention device are described. In an embodiment, the retention device includes a retention base having a stem protruding outwardly from a first surface of the retention base. Additionally, the retention device may include a retention closure configured to engage the retention base, the retention closure having a hole for receiving the stem. The retention device may also include a receiver coupled to the stem, the receiver configured to receive a retention member for retaining the retention closure in engagement with the retention base.
