ABSTRACT:
A transparent coupling for joining the ends of relatively soft plastic conduit. Visual inspection through the coupling affords confidence that the conduits have been installed in their proper position within the coupling. Internal circumferential barbs of the coupling penetrate the conduit and secure the conduit within the coupling and also provide a seal between the conduit and the coupling.
