Abstract
A connection of first and second members wherein each has a body and a connecting end with an inner surface so the second connecting end has an outer surface shaped for telescoping into the inner surface of the first connecting end. A shoulder is located on the second member and a groove is in the outer surface of the second connecting end. A raised nub on the inner surface of the first connecting end is radially inward to engage the groove. An elastomeric gasket is positioned to bear against the shoulder and be compressed between the first and second bodies. An engaging trough in the groove holds the first connecting end against the shoulder with the nub against the groove by the compression force of the gasket. An indexing trough in the groove positioned along the groove beyond the engaging trough allows the nub to follow therethrough and slightly compress the gasket thus giving the user a tactile indication that it has been rotated beyond the engaging trough. A method for fluid tight attachment of members of a medical device has steps including providing the connection of the first and second members with ends by telescoping the ends. Locating a groove for operating the groove a…
