Definitions
The phrase 'belt and braces' refers to taking extra precautions to ensure that something is secure or safe, often by using two or more methods for the same purpose, even if one would be sufficient. It originates from the idea of wearing both a belt and suspenders (braces) to hold up one's trousers.
