ABSTRACT:
A coupler to connect spaced apart ends of a pair of aligned shafts of an odometer assembly, for example, a shaft supporting permanent or total mileage indicating wheels and another shaft supporting trip indicating wheels. The coupler has a generally tubular body with spaced side walls, each side wall having a slot to receive an adjacent shaft end which is configured with a pair of ground flats. The coupler also has an integral catch portion with a movable end portion adopted to pass between the spaced shaft ends when the coupler is inserted over the shaft ends and subsequently to expand outward for preventing removal of the coupler.
