Abstract

A multi-barbed connection suitable for use in connecting a piece of flexible irrigation tubing is provided, where one of the barbs is a circumferential barb configured for forming a generally fluid tight connection with the tubing and another of the barbs is a corner barb having one or more corners configured for biting into the tubing for at least partially assisting in retaining the tubing on the connection. The connection can be part of a fitting for fluidly joining multiple pieces of tubing or part of an irrigation device, such as a pop-up irrigation sprinkler.

Claims

3-1. The barbed connection of claim 3, wherein the second maximum radius is greater than the corner maximum radius.
