A duplex electrical connector constructed of two body portions with internal bores. The body portions easily assemble and disassemble in a sliding manner, the direction of the assembly and disassembly being substantially at right angles to the axes of the internal bores. A front connector body includes a leading end and a trailing end with a lip, a trailing flange, and a bottom periphery. A tab with an aperture therein extends from the top lip. A rear connector body includes a leading end with a front extension, a boss, a trailing end, and two internal bores extending from the trailing end to the leading end. Sliding assembly of the connector bodies enables minimizing the size of the connector bodies for reducing unit production costs while enabling easy disassembly of the two connector body portions for inspection of internal cable connections.
