ABSTRACT:
A socket of a tube coupler is manufactured in the following steps: A rectangular steel plate is formed with pin-guiding lock grooves which are arranged at equal longitudinal intervals after the plate has been wound. The plate is wound as a single layer along the longitudinal direction thereof to form a tubular body. When the tubular body is used as a connector between a socket main cylinder and a socket adapter and when the socket adapter is fitted closely in one end portion of the tubular body, the other end portion of the tubular body is fixedly fitted in the free end portion of the socket adapter. Thereafter, the pins are fixed to the outer periphery of the socket main cylinder, through the respective lock grooves, so that a socket is manufactured. When, on the other hand, the tubular member is used as a socket main cylinder, the lock grooves are formed so that one end of each thereof opens at one end of the socket main cylinder, and a socket adapter is connected to the other end of the socket main cylinder to form a socket. A plug having the pins is guided by the lock grooves to be inserted into the socket.
