Abstract
A push pin device comprises a pin having a tip and an outer member coupled to and extending at least partially around the pin. The tip of the pin is located inside of the outer member in a retracted position when the outer member is uncompressed. The tip of the pin is located outside of the outer member in an extended position when the outer member is compressed. In the exemplary embodiment, the pin extends from a first portion of the outer member toward a second portion of the outer member and the first portion contacts the second portion when the outer member is compressed. When the first portion is seated in the second portion, the second portion applies an opposing force against the first portion to facilitate removal.
