Abstract
An adjustment control device for a chain. The control device includes a body member having a first orifice for slidably receiving the chain and a second orifice extending crosswise of the first orifice for receiving a shackle of a lock. After a chain has been inserted into the body member, the shackle of the lock is inserted into the second orifice between two alternate links of the chain without passing through the link connecting those alternate links to lock the chain in position.
