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 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.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
214 words
A device for coaxially connecting drainage tiles and the like having external, circumferential channels which comprise: a sleeve member having a first end 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 means is for securing together the first and second ends in overlapping relation, said means including a first tab adjacent the first end of said sleeve member, the first tab extending from a first side of said sleeve member and being adapted to be received within a circumferential channel in a corrugated drainage tile, the first tab having an interior chamber including an opening at the second side of said sleeve member, said means further including a second tab adjacent the second end of said sleeve, the second tab extending from the first side of said sleeve member and adapted to be received within the interior chamber of the first tab.
Claim 2
Independent Claim
214 words
A device for coaxially connecting drainage tiles and the like having external, circumferential channels which comprise: a sleeve member having a first end 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 means is for securing together the first and second ends in overlapping relation, said means including a first tab adjacent the first end of said sleeve member, the first tab extending from a first side of said sleeve member and being adapted to be received within a circumferential channel in a corrugated drainage tile, the first tab having an interior chamber including an opening at the second side of said sleeve member, said means further including a second tab adjacent the second end of said sleeve, the second tab extending from the first side of said sleeve member and adapted to be received within the interior chamber of the first tab.
Claim 3
Dependent Claim
45 words
The device of claim 1 in which the second tab has an enlarged head portion greater in size than the opening, whereby the second tab is held within the first tab when the enlarged head portion is inserted into the interior chamber beyond the opening.
Claim 4
Dependent Claim
60 words
The device of claim 1 in which said sleeve member includes a plurality of tabs spaced along the length between the first and second ends of said sleeve member and further includes a plurality of tabs spaced along the width of said sleeve member, each of the tabs being adapted to be received within circumferential channels in corrugated drainage tiles.
