Spring fastening clips suitable for 12mm, 16mm and 20mm poles and bamboo canes (Spring Clips: 12mm (Pack of 20))

They are excellent for making a frame from poles

Excellent for keeping canes together at right angles. We built a fruit cage.

I decided to change how I grow my tomatoes this year in the greenhouse, and bought some of the green plastic coated poles from my local garden center to build a framework in an oblong grid fashion. I will then grow the plants up string which hangs from the top horizontal bar. I have used some clips similar to this on a netted cage I bought to cover my veg plot. These work perfectly with the poles I bought - were so quick and easy to put together (and take apart), are really sturdy, and look the part. And if you want to adjust them it is easy. No fussy tying bamboo canes together for me! My plants in the greenhouse are going to love it. This would also work really well if you wanted to build a cage over fruit bushes etc.
