Patent ID: 6908118

Claim:
A socket for a dialyzer that connects a plug of the dialyzer and a dialysate tube for supplying or discharging a dialysate, wherein the socket comprises a socket main body having a coupling part to be fitted onto the plug of the dialyzer and a cylindrical part for connecting the dialysate tube, an outer sleeve fitted onto the coupling part of the socket main body, and a spring-biased holder for pressing a locking ball, the holder being accommodated between the socket main body and the outer sleeve and capable of moving back and forth, and the socket is capable of being attached to or removed from the plug with a single operation because of the locking ball being temporarily released by the holder moving back and forth when the socket is to be attached to or removed from the plug, and a front end portion of the holder constituting a protrusion that eternally protrudes from a front end surface of the outer sleeve, so that when cleaning the socket, the locking ball can be released by pressing said protrusion of the holder to retract the holder, thereby canceling a constraint state of the locking ball.
