Abstract
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 tabs which extend from a first side of the sleeve member and are received within the external, circumferential channels in the drainage tiles. One end of the sleeve member includes connecting tabs which are adapted to be received within openings located at the end of the sleeve member. 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 connecting tabs into the respective openings in the sleeve member.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
156 words
A device for coaxially connecting drainage tiles and the like having external, circumferential channels which comprises: a sleeve member having a first end and a second end, said sleeve member including a plurality of spaced apart tabs extending from a first side of said sleeve member and adapted to be received within the circumferential channels in coaxial, corrugated drainage tiles; and means for securing the first end of said sleeve member adjacent to the second end of said sleeve member to secure said sleeve member about the corrugated drainage tiles with the tabs received within the circumferential channels of the corrugated drainage tiles, said securing means including extensions located adjacent the first end of said sleeve member and extending from the second side of said sleeve member, said securing means further including apertures defined by said sleeve member and adjacent said second end of said sleeve member, the apertures being positioned to receive therein respective extensions.
Claim 2
Independent Claim
156 words
A device for coaxially connecting drainage tiles and the like having external, circumferential channels which comprises: a sleeve member having a first end and a second end, said sleeve member including a plurality of spaced apart tabs extending from a first side of said sleeve member and adapted to be received within the circumferential channels in coaxial, corrugated drainage tiles; and means for securing the first end of said sleeve member adjacent to the second end of said sleeve member to secure said sleeve member about the corrugated drainage tiles with the tabs received within the circumferential channels of the corrugated drainage tiles, said securing means including extensions located adjacent the first end of said sleeve member and extending from the second side of said sleeve member, said securing means further including apertures defined by said sleeve member and adjacent said second end of said sleeve member, the apertures being positioned to receive therein respective extensions.
Claim 3
Dependent Claim
