If you can find a solvent for the plastic (dichloromethane, sold as 'plastic weld' is a good one to try first) then what I do is :

Put the pieces together

Run a brush dipped in the solvent along each of the cracks. The solvent is drawn in by capillary action and will cause the plastic to weld along the cracks. DO NOT push the pieces together hard when doing this you do not want to squeeze out the softened plastic. Use a natural bristle brush, some of the synthetic bristles disolve in said solvent with unpleasant results.

Now take a piece of cotton fabic and cut it to cover the back of the repair area. An old cotton dress shirt will be fine, or a good sewing shop will have something (maybe an offcut, which iwll be cheap). Put that over the back of the repair area and 'paint' it with the solvent. When the plastic has softened, force the fabric into the softened area.
