ABSTRACT:
To prevent possible misalignment of the various parts of a plug and receptacle connector, if the coupling ring is inadvertently rotated before the receptacle is in full position, there is provided an interlock sleeve. This sleeve is spring-loaded and positioned between the coupling ring and the plug outer surface. Internal and external keys incorporated within the sleeve prevent inadvertent rotation of the coupling ring until the receptacle has made entry into the plug sufficiently to key both the coupling ring and plug shell.
