Abstract: Provided is a key chain including a body defining a cavity that is accessible through a sleeve connected to the body. An insert member inserts through the sleeve to engage a biased button member that is movably disposed within the cavity. The button member defines an aperture that receives a portion of the insert member and the button member moves between a first position and a second position to selectively latch and release, respectively, the insert member to the body. The sleeve protrudes into the button aperture to restrict movement of the button member. A first key ring is attached to the body and a second key ring is attached to the insert member, whereby the key rings are disconnected when the insert member is withdrawn from the body and the key rings are connected with the insert member is inserted into the cavity and latched to the body.

Abstract: An object retention apparatus which includes, in its most preferred embodiment, an outer body member and an inner body member, which inner body member is insertable into the outer body member and includes an interior storage compartment closed by a cap to seal in solids, such as heart medication tablets or diabetes medication and which is preferably designed to additionally seal a container or vial which fits within the compartment for storing liquids, such as perfume, cologne, breath freshener, etc. The object retention apparatus also features two attachment rings attached to the body members and a quick release mechanism to allow separation of the two body members and, thus, the rings. The quick release mechanism includes a push button, a retaining loop, a biasing device, and a retaining ring device for holding the release mechanism in place. In an alternate embodiment, the inner body consists of a whistle. The quick release mechanism also has application in other devices unrelated to object retention.
