<p>The key ring consists of a circular ring having a first complete coil and a section of a second coil elastically returned against the first coil. The two coils are separated by an interstice extending between the two free ends (4,5) of the two coils and between them. The interstice through which the key is passed to be fixed on or removed from the key ring has a nail shaped tenon (9') having a leading edge sufficiently thin to be inserted into the interstice and sufficiently wide to space apart the two coils to allow the key to pass when the tenon is rotated. A small ring (12) fixes the tenon to the key ring by hooking in an opening (8') in the tenon.</p> |
