Abstract: A key-retaining system is provided which includes a key holder and a key holder retainer. The key holder is a substantially continuous member having ends and sides, for example one continuous wire, and provides an interior space between the sides and ends of the member. The ends are separated by a predetermined distance substantially greater than the length of a key. One of the sides or ends includes a device to permit fastening of keys upon the member. The key holder retainer includes a hollow extending substantially from end to end of the key holder retainer and adapted to receive the key holder in use. Keys may be fastened on the key holder and positioned in a flat position within the interior space of the key holder. The key holder retainer is then friction fit onto the key holder remote the key heads.
