I have used super glue 'activated' with a pinch of baking soda to glue broken ABS plastic back together on a number of ocassions, but it has normally been small panel type repairs affixing tabs to snap-on panels that had broken off and that sort of thing.

Of note too, there are two dif types of 'PVC' solvents & glues sold for use with plastic pipe, so you may wish to try both. One of them works on ABS type plastics.
