A vent cap having a quick release fastener for connecting the vent cap to a flue pipe of a furnace or other such combustion system is disclosed. The fastener is designed for attachment to a tubular stub connector of the vent cap and has a clip portion for engaging a slot in the flue pipe to lock the vent cap and flue pipe tigether between the clip portion and a shoulder portion of the fastener. The vent cap is easily disconnected from the flue pipe by rotating the vent cap about the longitudinal axis of the flue pipe to remove the clip portion of the fastener from the slot in the flue pipe and then, pulling the vent cap apart from the flue pipe.
