A latching mechanism, which is configured to enable a pluggable optical transceiver module assembly to be plugged in or unplugged from a cage, is disclosed. The pluggable optical transceiver module assembly includes a bail clip for providing a latching portion locked in a locking member and an optical transceiver module having a connector portion including receptacle portions for accommodating external connectors. The bail clip includes a main body assembled through first and second ends of the connector portion; a lock pin, which is supported by a first end portion of the main body, has the latching portion exposed from or sunk in the second end of the connector portion, and provides a force of restitution to the bail clip; and a bail, one end of which is supported by a second end portion of the main body and which is laid on the first end of the connector portion in a lever shape, sinks the latching portion by giving pressure to the other end, and exposes the latching portion using the force of restitution of the lock pin by removing the pressure from the other end.
