US Patent 8408929 Guard for connection point of adjoined wire connectors

A cylindrical guard is used for protecting the electrical junction between connectors. The guard is essentially two split cylindrical sections oriented end-to-end with breakaway tabs therebetween. The split cylindrical pieces are hinged, and substantially irreversibly lock together in a “clamshell” like fashion. The resulting guarded junction is less likely to be accidentally disengaged, thereby protecting both property and life. The guard can be removed by cutting, or broken and moved to expose the underlying junction by severing the breakaway tabs.
