ABSTRACT OF THE INVENTION A solenoid valve assembly includes a valve body and an outwardly extending core tube assembly comprising a core tube, a fixed pole piece and a slidable plunger for actuating a valve in the valve body. An electromagnetic coil assembly comprising a flux frame and cylindrical coil is slidably and removably sup- ported on the core tube and is secured in place by a contractible ring with a shoulder engaged in a groove in the outer end of the core tube. The ring is an injection molded plastic part and is split, having a tongue and socket interconnection with plural ratchet teeth thereon to provide adjustable constriction of the ring. A pair of integral spring fingers are provided on opposite sides of the ring to axially bias the coil assembly against the valve body.
