A mounting assembly for supporting electrical apparatus such as transformers and the like on a utility pole includes spaced, equipment supporting brackets that are interconnected and secured to the pole by means of elongated, toothed plates. End regions of each plate extend through corresponding apertures in the brackets, and during assembly the end regions are shifted laterally and toward a narrowed portion of the aperture until a marginal edge section of the bracket next to the aperture enters a notch between adjacent teeth of the plate. The width of the narrowed aperture portion, being smaller than the overall width of the end regions of the plate except for the notches of the plate between adjacent teeth, prevents unintentional withdrawal of the plates from the brackets. A retaining spring, fixed to the bracket adjacent each aperture, ensures that the end region thereafter remains in place in the narrowed aperture portion in order to facilitate handling of the mounting assembly during installation.
