Abstract
An improvement for a safety lock is provided which is especially useful in a double cylinder lock having a longitudinally split lock web ring, wherein the ring has a releasable interlocking connection in the form of a hinge at one side and a pair of radially extending pegs on an opposite side which can be clamped together by a retainer in the form of a washer or a clamp to secure the two halves together. If a washer is used, the pegs may have to be swedged over, but if a clamp is used in the form of a resilient member surrounding a portion of the lock ring, no swedging is required.
