The sterile sleeve/connector assembly includes a joint formed between a sterile sleeve and a connector. The sleeve is made of a tube of thin flexible material, the connector includes a hub having an annular groove therein, and the joint includes an O-ring which is positioned within a bight of an inwardly inverted end portion of the sleeve and within the groove of the connector hub. The apparatus used in forming the assembly comprises a barrel member having a lumen, a distal end and a proximal end. The barrel member has a diameter approximately equal to a diameter of the hub the connector and less than the diameter of the sleeve. The method for using the apparatus comprises the steps of (a) pushing the O-ring onto an outer surface of the barrel member at the distal end of the barrel member; (b) sliding a sleeve over the barrel member; (c) inverting an end portion of the sleeve into the distal end of the lumen of the barrel member; (d) sliding the hub of the connector into the inverted end portion of the sleeve at the distal end of the lumen; (e) forcing the O-ring off the distal end of the barrel member, into a bight of the inverted end portion of the sleeve and into the annular groove in the hub of the connector; and (f) removing the connector from within the barrel member and pulling on the connector until the entire sleeve is removed from over the barrel member.
