The color coded safety master link (1) is a modified master link (1) used in endless roller chain drives (2). The invention allows the master link (1) to be safely and quickly located while at the same time indicating the size of the endless roller chain (2). An extended first pin (4) and extended second pin (5) are connected to a first pin link plate (9). A second pin link plate (14) engages the extended first pin (4) and extended second pin (5). A color coded extension pin link plate (6) engages the extended first pin (4) and extended second pin (5). A locking pin link plate is provided for securing the extension pin link plate (6) to the extended first pin (4) and extended second pin (5) allowing the master link (1) to remain in place when the roller chain drive (2) is in operation.
