Abstract

A chain lock for roller chains is rotationally controlled between lock and release modes. In the release mode, the device can be slid along the chain, and in the lock mode, it is fixed in position along the chain. The device comprises a locking arm which is rotatable by a handle so that in the in the lock mode, an end of the locking arm is seated in the space between adjacent rollers of the roller chain.
