The sides were at each other from the first blast of the whistle, looking to play attacking football and take an early lead.
Egyptian striker Amr Gamal came close in the eighth minute, his header going just on the wrong side of the upright.
Chippa struggled to create chances and looked most threatening breaking at pace.
The Clever Boys were unable to convert any of the chances that fell their way in the opening half and went into the break level with the visitors.
The deadlock was broken in the final quarter of an hour when Samuel Julies slotted a driven shot past Keet at full stretch in the 76th minute.
Julies doubles the Chilli Boys lead 10 minutes later with a superb effort from the edge of the area, dipping and curling into the top left corner.
