A connector for connecting non-metallic sheathed cable of both the round and oval types to electrical boxes in which the connector is of all plastic, one piece construction, free of clamps and screwing, and comprises a ring shaped segmented body defining a collet like cable gripping portion comprising a plurality of pairs of opposed resilient jaws in which the jaws each comprise a finger having a split base portion projecting from one end of the body and a jaw head directed laterally of and toward the body axis such that the jaw heads are grouped together, collet fashion, in spaced apart relation. The collet jaws are shaped to integrally connect together the body segments for reducing the diameter of the body for application purposes, and the jaws are formed for snap fit mounting of the connector in a knock-out opening of the box, they being arranged to be sprung apart to accept and pass the end of a cable being thrust through the connector for reception in the box. The jaws act to be drawn together and set against the cable when the cable is subject to movement tendencies outwardly of the box, to hold the cable end within the box, and without requiring clamps or crimping devices in connection therewith.

A connector for connecting non-metallic sheathed cable to electrical boxes in a knock-out opening thereof, said connector comprising: an annular body formed from a resiliently flexible material, said body defining a ring shaped portion at one end of same and a collet comprising a plurality of opposed resilient jaws in spaced apart relation about the axis of said body at the other end of same, said jaws each comprising a finger having a base connected to said body ring shaped portion and a jaw head directed laterally of and toward said axis, with said jaw heads being disposed substantially transversely of said axis and converging toward said axis in a substantially common plane that is disposed normally of said axis, with said jaw heads being similarly spaced from said body ring shaped portion thereabout, said jaw heads defining outer sides facing away from said body ring shaped portion and inner sides facing said body ring shaped portion, said jaw heads at their respective terminal end portions each defining a blunt cable gripping edge, with said edges being directed toward said axis in confronting relation therewith in closely spaced relation thereabout, said jaw heads being oriented and spaced about said axis to be cammed away from said axis, when one end of either oval or round non-metallic sheathed cable is passed through and body ring portion and is thrust against said inner sides of same, at random positioning about said axis, to separate said jaws and pass the cable therebetween with said jaw gripping edges disposed in sliding relation to and being resiliently biased against the cable, and draw said jaws, by way of the frictional engagement of their gripping edges with the cable, toward said axis into indented collet type gripping relation with such cable on movement of the cable end in the opposite direction, said fingers at their said outer sides defining means for snap fit mounting of said body in the box knock-out opening between said ends of said body adjacent said finger bases, with said inner sides of said jaw heads facing outwardly of the box and said heads disposed within the box, whereby the cable end may be inserted into and through the connector by pressing the cable end against the jaw head inner sides to cam the jaws apart for sliding the cable therebetween, said jaws resiliently seat against the cable, and said jaws oppose withdrawal of same from the connector by being closed against the cable on tendencies of same to move outwardly of the box.
