Abstract
Abstract A CPA device located entirely on a first connector of a pair of interfitting connectors, wherein the CPA device is actuable only in the event that the two connectors are actually mated. A slide slides between a prestaged position and a staged position. The latter position is attained only upon release of a CPA actuation lock which automatically occurs upon mating of the connectors. The slide is then slid to the staged position, whereat the slide interferes with a clasp mechanism of the connectors so as to prevent unintentional release of the clasp mechanism.
