An electrical connector has a connector body (200) with a bore (202) and a cap (100) through which a stranded insulated conductor (222) is threaded. A ridge (118) in the external surface of the cap engages with at least one groove (232) in the bore to secure the conductor in place. Preferably, there are at least two such grooves (232, 240) in the bore at different axial positions, and the cap (100) is axially advanced from one such groove to another one farther inside the bore to effect full physical and electrical connection. Surface pairs make up each such pdge and groove, with the area of one of the surface pairs being much greater than the other one of the surface pairs. The connector may have multiple bores (1438, 1424) and caps (1404, 1406), and embodiments are provided for coaxial conductors. Insulated conductors, of either the wire or multistranded cable variety, are provided with a series of markings (2516, 2518) or visual indicators along their length on their insulation jackets. The markings include cut markings (2516, 2518) to show where the conductor is to be cut and, spaced from respective ones of the cut markings by a predetermined insertion depth, insertion markings.to show a correct depth of insertion into an associated electrical connector receptacle (2702). Depending on the type of connector for which the conductor is being furnished, the markings may further include a plurality of strip markings (2704), spaced from respective ones of the cut markings by a predetermined strip length, and/or a plurality of final insertion markings, which are spaced from respective ones of the initial insertion markings by a predetermined connector cap (2710) compression stroke.
