Tool locking mounting shell for protecting electrical connections in a hazardous environment

A connector assembly for electrical contacts, comprising:

• a plug housing configured to receive a first electrical contact;
• a receptacle housing configured to receive a second electrical contact that is configured to couple to the first electrical contact, the receptacle housing including a mounting shell;
• and
• a locking mechanism mounted on the mounting shell and configured to couple the plug housing with the receptacle housing, wherein the receptacle housing is configured to engage with the plug housing when the locking mechanism is at a locked position, the receptacle housing is configured to disengage from the plug housing when the locking mechanism is at an open position, and the locking mechanism further comprises a tooled actuator configured to lock the locking mechanism when the locking mechanism is at the locked position, the tooled actuator sized to require a tool to operate the tooled actuator to lock the locking mechanism when the locking mechanism is at the locked position.
