A labor saving system, method, and apparatus for connecting or coupling lengths of electric metallic tubing ("EMT"). The invention uses couplings/connectors that have barbs that are designed to engage corresponding indentations on EMT to ensure proper installation. In one aspect, the invention is an EMT having: an EMT inner surface forming an EMT cavity; an EMT outer surface; an EMT first end; and at least one indentation in the EMT outer surface at or near the EMT first end, the indentation adapted to receive a corresponding barb from a sleeve device. In another aspect, the invention is a linking device for EMT comprising: a first section having a link inner surface forming a link cavity adapted to receive an end of an EMT, a link outer surface, and at least one barb access hole adapted to allow a corresponding barb of a sleeve device to extend therethrough when the sleeve device is fitted around the first section; a second section; and a separator between the first and second sections.
