Guide rails, projecting axially from a housing section flange, are received in apertures provided therefor in a mating housing section flange, whereby the latter will be concentrically directed, into engagement with the former. Each housing section contains a magnet-carrier assembly which, otherwise, would be magnetically attracted to the other, and occasion damage or injury during assembly or disassembly. The rails prevent radial dislacement of one of the assemblies relative to the other thereof. In addition, jacking screws are interposed between the flanges to insure that magnetically-induced impacting engagement will not occur between the flanges.
