A latch assembly includes a latch unit which can be used with a circular or rectangular faceplate unit. The circular faceplate unit includes a faceplate, a first casing half integral with the faceplate, a second casing half releaseably attached to the faceplate, and a retention ring disposed around the first and second casing halves which surround a housing of the latch unit. The first and second casing halves have slots to engage bosses projecting from a housing of the latch unit. A backing plate of the rectangular faceplate unit has a tubular wall with an engaging hole. The boss of the housing can be slid axially in the engaging hole and then rotated for engagement therewith.
