female connector 67 by means of lock rings 60 which are secured in annular lock ring groove 68 about female socket portion 66 and abut internal shoulder 15 of sleeve 62 as sleeve 62 is biased by spring 63 to a forward locking position when in locking position retaining balls or pins 64 are retained in an inwardly biased position by contact with axially flat annular portion 81 of sleeve 62 so as to partially extend into the media channel 71 when sleeve 62 is manually influenced against the bias of spring 63 to a rearward position by engagement between the spring and radially flat annular portion 75 balls or pin 64 are disposed adjacent annular tapered portion 70 or larger diameter annular portion 16 of sleeve 62 which permits balls or pins 64 to move radially outwardly so as to be removed from inside media channel 71 o rings 61 are disposed within respective o ring grooves not shown male and female connectors 31 and 67 removably couple together by forcing sleeve 62 to the rearward position against the bias of spring 63 such that retaining balls or pin 64 can clear the media channel 71 when the male coupling portion 50 which fits closely in media channel 71 is moved into position in media channel 71 when male and female connectors 31 and 67 are rotated relative to one another to the proper position or otherwise interconnected anti rotation ridge or ridges 52 each fit into a region 17 between two adjacent retaining balls or pins 64 the respective surfaces thereof on opposite sides of region 17 being thereby engageble by ridge 52 as shown in fig6 to prevent such relative rotation male coupling portion 50 is moved into the opening in female socket.
