Abstract
Abstract An electric connector employs a coupling device comprising a connecting ring having head portions and provided in a receptacle part, and a tubular body, an outer tube surrounding the tubular body and a spring located between the tubular body and the outer tube, said tubular body, outer tube and spring being provided in a plug part. When the receptacle part is fitted to the plug part, the outer tube is longitudinally retracted against the spring by the head portions of the connecting ring. Then, when the head portions of the connecting ring fall into outer recesses provided in the tubular body, the outer tube returns to its original position to keep the head portions of the connecting ring fitted into the outer recesses, thereby the receptacle part is kept coupled to the plug part. The outer tube can be longitudinally retracted to release the coupling of the receptacle part with the plug part.
