Unitary piece dual lock split washer

A unitary piece dual lock split washer comprising:

• a single piece body made of a resilient and flexible material, the body having an inner circumferential edge, a radially outer peripheral edge and a split extending between the inner and outer edges to provide the body with first and second ends;
• and
• a joint structure integrally formed with the first and second ends, the joint structure having an engaged state wherein the first and second ends mutually engage each other to form a substantial seal across the split, and a disengaged state wherein the first and second ends can be moved apart to create an opening of a variable size and shape in the body to enable the washer to be fitted about a member, the joint structure having a first locking mechanism and a second locking mechanism each locking mechanism having respective parts on the first and second ends and wherein the parts of the second locking mechanism are only engageable after the parts of the first locking mechanism are fully engaged;
• wherein the joint structure includes:
• first and second fingers radially spaced by a first gap and extending circumferentially from the first end;
• and, first and second fingers radially spaced by a second gap and extending circumferentially from the second end wherein when in the engaged state one finger of each end fits in the gap between the two fingers of the other end.
