A continuous, flexible, helical wire conduit is terminated at predetermined cut-off points along its length by the steps of molding around the conduit adjacent said predetermined cut-off points, cylindrical termination members of thermoplastic material. The plastic members are molded onto the continuous conduit by injection molding at a sufficiently high pressure that the plastic penetrates into the recessed portions between adjacent helical coils, thereby assisting in sealing the interior of the conduit against corrosive liquid. In addition, the flexibility and length of the termination members are chosen to distribute vibration or bending stress along the termination members when the conduit is inserted into a fitting and thereby to reduce the concentration of stress at the conduit exit point. Conveniently, the termination member is provided with a reduced diameter at the predetermined cut-off point in order to minimize cut-off burrs.
