Abstract From the Canadian patent

A connector for engaging non-metallic liquid-tight conduit includes an inner ferrule having a cylindrical portion with an annular rib dimensioned to be inserted into the end of the conduit, and a surrounding sleeve having a conical outer surface and axially extending slots. The sleeve surrounds the conduit and is engaged by a compression nut which radially inwardly decreases the radius of the sleeve, engaging the conduit between the smaller compressed end thereof and the annular rib on the ferrule. The connector also includes a body with threads to engage the nut and the ferrule and body include means for limiting rotational motion of the ferrule.
