An apparatus comprises a housing comprising a housing first portion and a housing second portion. The housing first portion comprises a first joint portion overlapping a second joint portion of the housing second portion so as to form a housing joint. A clamp is positioned on the housing joint and comprises a base portion. A first surface of the base portion is positioned on the housing joint. A plurality of legs extend from the base portion towards the housing each of which are spaced from each other around the housing joint. A plurality of flange segments extend from each side of the base portion away from the housing. A band is positioned on a second surface of the base portion opposite the first surface and around the clamp. The band is positioned between the plurality of flange segments and operatively coupled to the housing via the clamp.
