In one embodiment of the key holder the plunger element is engageable with a releasable pin element having a key ring thereon for releasably retaining the pin element and the key ring in assembled relation with the body portion. In a second embodiment the plunger element is engageable with a pin element attached to the body portion for retaining an open ring element attached to the pin element in a closed position wherein a key receive on the ring element is retained thereon. The plunger element in the second embodiment is depressible to permit pivoting of the pin and ring elements to an open position wherein a key received on the ring element is removable therefrom.
