ABSTRACT:
A closure for securing conductor bars in the coil slots of a dynamoelectric machine consisting of a U-shaped clip which is inserted into the coil slots over the conductor with the legs of the clip extending between the sides of the conductor and the winding slot. Spring-like tabs which, in the preferred embodiment, are the lower portion of the legs bent upward, snap into longitudinal grooves provided in the side walls of the conductor slot when the top portion of the U-shaped clip contacts the top of the coil sides. This permits insertion of the slot closure from the top of the slot by merely pushing downward until the tabs snap into the side grooves.
