ABSTRACT:
A coupling socket includes a main cylindrical body and a locking member. The main cylindrical body has a hole extending along its longitudinal axis and a rectangular hole formed on its plug-inserted portion and directed perpendicular to its hole. The locking member includes locking parts provided with ring-shaped pieces engageable with a locking groove on a plug. A plug hole is formed between the locking parts when one of the ring-shaped pieces is placed on the other. The plug hole is made wide when the locking parts approach each other and narrow when they separate from each other. The locking member is fitted into the rectangular hole of the main cylindrical body in such a way that the plug hole is aligned with the hole and that the locking parts is controlled from outside of the main cylindrical body to come close to and separated from each other. Springs are interposed between the main cylindrical body and the locking member to urge the locking parts to apart from each other.
