A structure for connecting an end fitting formed from a metallic material to a hollow cylindrical drive shaft tube formed from a composite material is disclosed. The drive shaft tube has an open end and an inner cylindrical surface. The end fitting includes a cylindrical sleeve portion having an outer circumferential surface which is formed having a plurality of longitudinally extending channels. An adhesive material, such as epoxy, is applied either to the outer circumferential surface of the sleeve or to the inner cylindrical surface of the bore of the drive shaft. Then, the sleeve portion of the end fitting is inserted within the drive shaft tube, with the outer surface of the sleeve portion engaging the inner cylindrical surface of the drive shaft tube in a light press relationship. The adhesive material flows into the channels between the sleeve portion of the end fitting and the inner cylindrical surface of the drive shaft. The adhesive material is cured to form an adhesive bond between the channels in the sleeve and the inner cylindrical surface of the bore of the drive shaft.
