ABSTRACT:
Disclosed is a retaining band for the magnetic core loop of an electrical transformer. The retaining band includes a locking mechanism to hold it in place around the core. The locking is accomplished by overlapping the ends of the band, cutting a pair of incisions in the overlapping region which extend from the sides of the band inwardly, and then bending the resulting tab(s) inwardly. If desired, the tabs can be spot welded to provide added locking force.
