ABSTRACT:
A key holder includes a keyring adapted to hold at least one preselected key, and a housing having an arcuate passage formed therein. The housing further has a notch formed in its outer periphery which is sized to receive the keyring and a first opening formed therein at one side of the notch which communicates with an end of the passage. A plunger having a flexible arm portion is disposed within the passage and movable between a position in which the flexible arm portion extends through the opening and across the notch for retaining the keyring to the housing and a position in which the flexible arm portion is withdrawn into the passage for allowing the removal of the keyring from the housing. The plunger is biased to its keyring retaining position, and the flexible arm portion is adapted to flex to conform to the shape of the passage when moving the plunger between its keyring-retaining and withdrawn positions.
