A terminal cover (A) includes an escaping portion (20) formed by cutting off a part of a peripheral wall portion forming a first accommodating portion (11) to allow an internal space of the first accommodating portion (11) to communicate with a second accommodating portion (12), thereby avoiding interference with a linking portion (53) of a terminal fitting (B). The terminal cover (A) also includes a multi-functional portion (26) which can be assembled with the first accommodating portion (11) and is arranged to close at least a part of the escaping portion (20) and capable of pressing the terminal fitting (B) to prevent a displacement of the terminal fitting (B) in an assembled state.
