A key chain, comprising:

• a first body having a first end and a second end and defining a compartment within said first body accessible from said first end of said first body;
• key retention means connected to said second end of said first body for attaching keys to said first body;
• a cap;
• cap retention means for holding said cap at a position which covers said compartment;
• a second body including, at least, a first end and a second end, and defining a compartment accessible from said first end of said second body and sized to closely accommodate said first body;
• and
• object retention means attached to said second end of said second body for attaching keys to said second body.

A key chain, comprising:

• a first body having a first end and a second end and defining a cavity within said first body accessible from said first end of said first body;
• key retention means connected to said second end of said first body for attaching keys to said first body;
• a second body for at least partial insertion into said cavity;
• and
• detention means for releasably holding said second body at least partially within said cavity,
• wherein said detention means includes, at least, a loop element attached to said first body, and means for moving said loop element between a first position in which said loop element engages said second body and a second position in which said loop element does not engage said second body.

A key chain, comprising:

• a first body having a first end and a second end and defining a cavity accessible from said first end of said first body;
• key retention means connected to said second end of said first body for attaching keys to said first body;
• a second body for at least partial insertion into said cavity;
• detention means for releasably holding said second body at least partially within said cavity,
• said second body having a first end and a second end and defining a cavity accessible from said first end of said second body;
• a cap for insertion partially into said cavity of said second body;
• and
• a hollow vial for insertion into said cavity of said second body, said hollow vial including an opening at one end and a bead around said vial opening,
• wherein said cap further includes, means for securing said cap to said second body and to said vial.

An apparatus, comprising:

• a body including, at least, a first and a second end and defining a cavity accessible from said first end of said body;
• object retention means connected to said second end of said body for attaching keys to said body;
• a flexible cap for insertion partially into said cavity;
• and
• cap retention means for holding said cap at a position which covers said cavity.

An apparatus, comprising:

• a first body including, at least, a first end and a second end and defining a cavity accessible from said first end of said first body and extending toward said second end of said first body;
• a second body including, at least, a first end and a second end and defining a cavity accessible from said first end of said second body and extending toward said second end of said second body;
• and
• detention means for releasably connecting said first body to said second body, with said second body at least partially inserted within said cavity of said first body, wherein said first body first end is adjacent to said second body second end and said first body second end is adjacent to said second body first end.

A key chain comprising:

• a first body having a first end and a second end and defining an open space accessible from said first end of said first body;
• key retention means connected to said second end of said first body for attaching keys to said first body;
• a second body having a first end and a second end and defining an open space;
• detention means for releasible holding said second body at least partially within said open space of said first body;
• a cap;
• and
• cap retention means for holding said cap at a position which covers said open space of said second body.

An object retention apparatus comprising:

• a body including, at least, a first end and a second end and defining a cavity accessible from said first end of said body;
• a cap;
• and
• cap retention means for detachably holding said cap in a position where said cap covers said cavity of said body, said cap retention means comprising, at least, an appendage for insertion into said cavity of said body, a ridge around said appendage, and a channel within said cavity of said body.

Coupling apparatus for releasably coupling a first body to a second body, the first body including a cavity for receipt of at least a portion of the second body, said apparatus comprising:

• a retaining loop slidably connected to and at least partially within a first body, said retaining loop defining an opening for receipt of a second body;
• an external means connected to said retaining loop for receiving from a user, and transferring to said retaining loop, force tending to slide said retaining loop in a first direction within the first body to release the second body;
• and
• a biasing means connected to said retaining loop for exerting force on said retaining loop tending to slide said retaining loop in a second direction opposite to the first direction to couple the second body.

An apparatus comprising:

• a first body including, at least, a first end and a second end and defining a cavity accessible from said first end of said first body;
• a second body including, at least, a first end, a second end, and means for creating a whistling noise by blowing through said first end of said second body;
• and
• detention means for releasably connecting said first body to said second body, with said second body at least partially inserted within said cavity of said first body, wherein said first body first end is adjacent to said second body second end and said first body second end is adjacent to said second body first end.
