The Hozelock Pro Metal Hose Joiner is a high quality metal hose connector for repairing damaged hoses or joining two lengths of hose pipe together. To repair a broken hose, simply cut the pipe to remove the damaged area and push both ends into the castle grip connectors on the hose pipe. Risks of the hose pipe swelling, kinking and bending are reduced through the flexible hose tails that are used on the connector that allow the hose pipe to move freely without affecting water flow. Suitable for use with 13mm (1/2") garden hose pipe only.
