ABSTRACT:
A electrical connector for connecting conduit or cables to a junction box. The connector includes a tubular connector body with a longitudinal slot extending substantially along the length of the connector body and dividing the tubular connector body into an upper half and a lower half. A lateral slot extends through the upper half of the connector body at the leading end thereby hinging the upper half to the lower half at the trailing end of the connector. A tubular snap ring including one or more locking tangs is disposed and held thereon on the leading end of the connector body by a spring bias. The trailing body portion includes a threaded aperture and a threaded fastener therein. When inserted into a knockout in a junction box, the leading end of the snap engagement connector is held firmly but adjustably therein by engagement of the locking tangs with the panel, thereby allowing the orientation of the connector with respect to the box to be adjusted as desired. A conduit may then be inserted into the trailing end of the connector and secured therein by the fastener. Tightening of the fastener upon the conduit forces the upper half of the connector body away from the lower half and spreads the leading end of the connector body and the snap ring into tight engagement with the electrical panel.
