A plastic gauge casing formed of separate front and rear cup-like interfitting sections. Concentrically arranged annular skirts on a first section define an annular recess therebetween. In assembly, an annular skirt on the second section is telescopically received in the recess contiguously in an interleaved relation with skirts of the first section. Mutually engageable radial tabs on opposite facing skirts provide an interlock against pullout.
