ABSTRACT:
A cylindrical case (8) is inserted hermetically into a first housing (1) of a socket (A), and the cylindrical case (8) is urged rightward by an advancing spring (9). A sliding cylinder (20) is inserted hermetically into the cylindrical case (8), and the sliding cylinder (20) is urged rightward by another advancing spring (28). As the socket (A) and a plug (B) are connected toward each other, a pushing member (65) arranged at the leading end portion of a second housing (2) of the plug (B) makes the sliding cylinder (20) retreat to an opening position on the left side as well as a first closing member (26) inserted into the sliding cylinder (20) pushes a second closing member (62) inserted into the second housing (2) to , an opening position on the right side.
