ABSTRACT:
A screw-on electrical connector for connecting the stripped ends of electrical wires has a shell made of stiffly flexible plastic material. A generally central bore extends from an open end of the shell to a closed end which is closed by an integral end wall. A generally tapered wire coil lies in the bore and engages an outer area on the inner surface of the bore, adjacent its open end. A radial undercut is formed on the inner surface of the bore near the end wall. The undercut projects into the bore to support the coil and to strengthen the shell.
