Abstract
A key holder has a rigid gapped ring 1, having a gap which is defined between two mutually facing tips, a thin-walled metal sheath 2 having, near one end, two transverse slots or apertures of asymmetric form permitting the transverse introduction of the tips 4 of the ring 1 from one side only of the sheath 2, i.e. the front side as seen in the drawing, and a slide 3 which is longitudinally slidable inside the sheath 2 and comprises at the position of each of the apertures 5 locking ribs situated on that side of the apertures 5 from which the tips 4 are introduced. The locking ribs partially mask the apertures to prevent the tips 4 from being removed when the slide 3 is slid into a closing position in which it is entirely housed inside the sheath 2. The slide is slidable downwards in the sheath to an opening position in which the ribs are clear of the slots or apertures to enable the ring to be removed and enable keys to be fitted to it or removed from it through the gap between the tips 4.
