ABSTRACT:
A generally tubular plastic collet, which is mounted coaxially in the bore of a rigid, tubular housing, has on one end thereof a plurality of radially flexible jaws that surround one end of an electrical cord that extends into the housing bore at one end thereof. A metal tip has an externally threaded shank that is adjustably threaded into the opposite end of the housing bore, and an elongate stem portion which projects to the exterior of the housing. The tip comprises a pair of coaxially disposed conductors insulated from each other in a conventional manner, and connected in the housing to a pair of wire conductors that project from the cord. The threaded end of the tip engages and urges the collet axially toward the inlet end of the housing, thereby flexing the collet jaws radially inwardly into gripping engagement with the cord.
