A dynamoelectric machine comprising a stator core with slots therein and top and bottom coils contained in each of the slots and extend from the end of the stator core is provided. A radial clamp for securing a pair of adjacent top coils together with a pair of bottom coils is provided. The radial clamp comprises a support block radially outside the pair of top coils. The support block has an aperture that is substantially radially lined in relation to the axis of the machine. A retaining platform is coupled proximate the bottom coils. The retaining platform defines a bore. A connecting insert member that is adapted to be adjustably mounted within the retaining platform bore is provided. The connecting insert member further defines an aperture. A traverse pin is mounted proximate the support block. A radially extending banding material having a first end and a second end which has a head portion is provided. The first end of the banding material is formed around the pin with the banding material running through the first support block aperture and with the head portion received within the connecting insert member aperture such that the connecting member can be adjusted to adjust the length of the banding material.
