  • Tab-lock fastener for interlocking vent pipe
    Patent number: 6811190
    Abstract: The present invention provides a tab-lock fastener for connecting first and second vent pipes typically used to exhaust products of combustion of natural gas appliances. The tab-lock fastener includes a guide and a tab-lock receptacle formed on a male end of the first vent pipe, an engaging tab formed on a female end of the second vent pipe, and a locking tab formed on the female end of the second vent pipe. The first and second vent pipes are assembled by inserting the male end of the first vent pipe into the female end of the second vent pipe so that the engaging tab is received in the guide and twisting one of the vent pipes with respect to the other vent pipe. The locking tab engages a wall of the tab-lock receptacle to prevent untwisting and unwanted disconnection of the vent pipes.
