Abstract: A customisable key holder for retention of at least one key; the key holder comprising two separate outer sheathing plates which store the at least one key between them; one or more removable locking pins utilising a locking mechanism to secure the at least one key between the outer sheathing plates; the key holder further including one or two interchangeable sheathing plate covers adapted for personalisation of the key holder; at least one of the interchangeable sheathing plate covers providing storage space for an accessory element.

Abstract: A separable, pull-apart key holder formed of two identically-shaped pieces. The pieces are mounted together in reversed, face-to-face relationship. The pieces are formed of a strong, rigid resiliently flexible plastic material, such as molded polycarbonate or nylon. Each includes a flat, plate-shaped body having a generally planar bearing surface on one side. Projecting tongues formed at one end of the bearing surfaces are received in openings formed at the opposite ends of the bearing surfaces. Locking notches snap into engagement to prevent accidental separation of the pieces after they have been pressed together. The pieces can be intentionally separated by simply pulling them apart with a quick tug or pull, causing the locking notches to deflect resiliently and release. The pieces are reassembled by simply pressing or sliding them together, longitudinal alignment between the parts being established by interfitting ribs and channels on the bearing surfaces.
