Abstract: A retainer for affixing an electromechanical device to adjacent motor vehicle support structure includes an locating pin integrally molded of relative hard material as an integral feature of the electromechanical device case. The locating pin includes parallel side walls forming an axially directed channel bifurcated by a tapered guideway and at least one inwardly facing engagement surface. The retainer also includes a relatively soft bushing clip having resilient arms slip-fit within said channel straddling the tapered guideway to self-lock with said engagement surface. The clip arms extend outwardly of said locating pin side walls and form opposed, axially extending bushing surfaces operative to engage vehicle support structure.
