Claims (7)

THE CLAIMS DEFINING THE INVENTION ARE AS FOLLOWS:

1. A sleeve for a dowel, wherein the sleeve is adapted to clip on to formwork through which the dowel is inserted, wherein the sleeve includes a flange for abutting against the formwork, a sleeve portion extending from the flange, an upper rib supporting the sleeve portion relative to the flange and a lower rib supporting the sleeve portion relative to the flange, and wherein the flange includes an upper flange portion for engagement with an upper rail of the formwork and a lower flange portion having resilient clips for clipping behind a lower rail of the formwork.

2. A sleeve as claimed in claim 1, wherein the sleeve includes surrounds around the resilient clips preventing dislodgement of the upper flange portion from the upper rail of the formwork.

3. A sleeve as claimed in claim 1 or 2, wherein the sleeve includes crushable internal lateral movement voids located at opposed sides of a cavity for receiving the dowel.

4. A sleeve as claimed in any one of claims 1 to 3, wherein the sleeve includes an expansion void.

5. A sleeve as claimed in any one of claims 1 to 4, wherein the sleeve portion includes internal ribs which provide interference on insertion of the dowel.

6. A sleeve as claimed in any one of claims 1 to 5 wherein the sleeve includes centering ribs which, when the sleeve is clipped on to the formwork, protrude into a dowel slot of the formwork to prevent lateral misalignment of the sleeve and the slot.

7. A concrete footpath formwork system including a sideform for forming adjacent concrete panels of a footpath, a dowel adapted to extend through the sideform for transferring load between the adjacent concrete panels, and a sleeve as claimed in any one of claims 1 to 6.
