Look like a tool used to open spring connectors.
If you mean like an automotive snap ring connector, it does function that way, but no. Think light fixture.
A broken incandescent lamp removal tool.

They are chain pliers. Either to open or close chain used to suspend lighting fixtures. Chain has links about 1" to 1 1/2" long.

Swag chain pliers.
I have a pair that are cast and gold color.
I've had them for 25 yrs.
Works good to spread and rebend fixture chain.
I should have known I couldn't stump this forum!!!!!!! Swag chain pliers they are.
