Abstract:
1. A key ring comprising a ring having a complete first turn and a second turn joined to and resiliently pulled towards the first turn, which is separated from the second turn by a gap extending between the two turns and between the two free ends thereof, the head of a key being passed through the gap so as to fix it to or remove it from the key ring, wherein a lug is provided with a leading edge sufficiently thin to be inserted into the gap and sufficiently wide, by rotating the lug, to move the two turns apart sufficiently to insert a key head between them, wherein an auxiliary ring is provided to fixate the lug to the ring, said lug having an opening through which passes said auxiliary ring, the relative dimensions of the auxiliary ring, of the leading edge and of the opening of the lug being selected so that, when the lug is rotated of substantially 90 degrees, with the leading edge inserted on its width in the gap, the auxiliary ring is in contact with the lug so that the rotation of the lug is not possible in one direction of rotation, the lug being then retained between the two turns so that a user can insert a key between the two turns without having to hold the lug, the internal diameter of the auxiliary ring being substantially equal or greater to the sum of the useful width of the lug and of the two thicknesses of the two turns, in a direction perpendicular to the plane defined by the key ring.
