Abstract
A connector for a helically corrugated conduit and includes a coupling mechanism defining a cavity for receiving an end of a conduit having external corrugations, and a stop surface disposed within the cavity; a hollow fastener threadedly engaged with the connector mechanism and defining an engagement surface; and a collar disposed in the cavity and having internal grooves adapted to engage the external corrugations on the conduit, the collar having an inner end surface for engaging the stop surface and an outer end surface for engaging the engagement surface, and wherein circumferentially spaced apart portions of the collar are split by longitudinally extending slot means. Forcible engagement between the connector mechanism and fastener produces circumferential contraction of the collar along the slot and radially against the outer surface of the conduit.
