skewer connector - spojka na špejle with a diameter of 2.5 mm

A simple connector for 2.5 mm diameter stakes (common in the Czech Republic)

I use it to extend stakes when pre-growing climbing plants

If you have trouble sliding it onto the skewer (due to the skewer not being the correct size), use a utility knife to cut through one side of the connector. This is not usually necessary, as the connector stays on the skewer quite well without the use of glue
