ABSTRACT:
A generally T-shaped clip is fit into notches formed in the field shell of a permanent magnet D.C. motor. The clip has a passageway formed through its top surface for receiving a screw or the like to secure the field shell to a surrounding tool housing. The notches have a top portion with an elongated portion that has a concave inner side to abut the outer surface of the field shell and retain the clip in the notches. The clip has a bottom portion that is bent so that it contacts the screw to prevent it from turning and loosening.
