The connector assembly includes a tab (362) for being received in a hole (242) of a bendable portion (240) of a receptacle (2), which receptacle receives the transceiver module therein. The driving device includes, a release member (42) and a wedge member (46). Both the pull tab and the wedge member are mechanically linked to the release member.
