A connector includes a jack and an attachment plug which inserts into a socket of the jack. The plug has a plug body with an attachment pin planted at its forward end and sinkable lock portions projecting from an outer circumferential surface of the plug body so that the sinkable lock portions return to their initial positions automatically by their own elastic force. The jack has an engagement portion formed along the inner circumference of the plug insertion inlet of the socket so that the engagement portion locks the lock portions when the attachment plug is inserted into the jack. The engagement portion is formed by folding an end portion of the socket at the plug insertion inlet.
