In order to overcome the disadvantage in paint rollers of the type in which the end portions of the fabric sleeve are reflexly foldably disposed within the end portions of the tubular member and are securely clamped therein that paint may operatively seep along the clamped reflexly foldably disposed end portions of the fabric sleeve and into the interior of the tubular member, there is provided a paint roller of the above-described type in which the clamping of the reflexly foldably disposed end portions of the fabric sleeve within the end portions of the tubular member is by means of tubular end collars which are disposed within these end portions of the fabric sleeve and the inner end portions of which are in substantially liquid-tight direct locking engagement with inwardly projecting annular ribs presented by the end portions of the tubular member.
