Abstract
A conduit connector includes an inner externally threaded member having an expanded medial hexagonal section, the opposite threaded end being engaged by nut members carrying compressible clamping rings. Each of the nuts is produced from a short length of cylindrical tubing or may be drawn from sheet stock whose outer section is expanded to form a hexagonal portion terminating in an inwardly directed lip and joining at its inner end an inner cylindrical collar section. The nut is then internally threaded to form a continuous thread in the collar section and an extending discontinuous thread on the inner face of the hexagonal section.
