Catalytic converters removal

[Robvespa]

Hi, new to the forum, does anyone know how to take the cat off, it’s snapped above the box and I can’t work out how to remove it, I’ve had it up on a four poster ramp with the front wheels off and can see it through the drivers (UK) side inner wing but I can’t see any nuts and bolts from underneath, it’s a 2005 Grand Scenic 1.9 dci, thanks in advance for any advice
