Abstract
Abstract A buckle for securing a conductive strap has a conductive base for skin contact and a non-conductive cover partially attached to the base, the base having upwardly extending sides and the cover downwardly extending sides encapsulating the sides of the base. A conductive attachment element is on the cover and a conductive clip member is within the cover in electrical conduct with the attachment means and with the base continuously when the cover is closed and open.
