You either need to make a new shape with an offset, or set the offset on the original shape. You might also want to adjust the mass and moment of inertia of the player character.

Thanks.

Though I'm considering using a joint, it would make things easier, but I can't quite figure out where to put the two anchors.
I tried a pinjoint, with the two anchors set to cpvzero, the object is grabbed correctly, but while moving, the object is free to rotate around the player, like it was connected by a rod. How can I make the joint stiff?

You'll need at least two joints to make it stiff, and that means that it won't really be that stiff. Not using joints would be simpler, faster, and more numerically stable.
