Abstract: A key ring comprising a preferably circular ring having a complete first turn 1 and a part of or preferably a complete second turn 2 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 3, 5 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 9 is provided in the form of a claw having a leading edge 10 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, and fixating means for fixating the lug at a distance from the ring sufficient to allow the insertion of the lug into the gap.
