ABSTRACT:
A key holder includes a holding strap composed of a row of coupling elements attached to a flexible core cord, each of the coupling element having a coupling head which is symmetric in shape about a longitudinal axis of said coupling element, an end stop mounted across opposite ends of the holding strap for connecting them while keeping the holding strap bent into a closed loop with the respective coupling heads of the coupling elements directed inwardly of the looped holding strap, and a slider slidably mounted on and movable along opposed ones of the coupling elements for taking them into and out of interdigitating engagement. With this construction, the loop of the holding strap can be adjusted by moving the slider to such an extent as to meet the user's desire or to conform to the number of keys to be held on the key holder.
