Abstract
A connector for firmly engaging the exterior annular ribs on non-metallic conduit includes a tubular sleeve with a stop wall at one end, the stop wall having an opening therethrough. Several latch tabs are formed in the side wall of the sleeve, the tabs being inclined inwardly so that the ends of them extend into the interior of the sleeve. When a piece of conduit is inserted until it abuts the stop wall, the tabs snap into recesses adjacent the end rings. On the other side of the stop wall are hook members to engage the opening in a junction box or an identical sleeve for engaging a second piece of conduit.
