    Abstract: Disclosed herein is a device for connecting corrugated drainage tiles and the like which comprises a sleeve member which fits around the adjacent ends of coaxial drainage tiles. The sleeve member includes first tabs at one end which extend from a first side of the sleeve member and are received within the external, circumferential channels in the drainage tiles. Each of the tabs defines an interior chamber which opens on the second side of the sleeve member. The other end of the sleeve member includes second tabs which are adapted to be received through the openings and within the interior chambers of the tabs on the first end of the sleeve member. The sleeve member includes several, additional tabs which are received within the external, circumferential channels of the drainage tiles. The sleeve member may thereby be positioned about the adjacent drainage tiles and the ends of the sleeve member are secured together by insertion of the second tabs into the respective interior chambers of the first tabs.
