protective shell
Hard outer covering
A protective shell is a hard outer covering that shields something vulnerable inside.
Literally, it's the calcified exterior of creatures like turtles, snails, or crabs.
Figuratively, it describes emotional defenses people build around themselves: After the divorce, she retreated into a protective shell.
The phrase suggests both safety and isolation—what protects also separates.
