In order to optimize my garden watering I bought several items Gardena and am consistently pleased with the processing and the simplicity of the system. To connect the Connecting Pipe you need it to push connector, the connector a quarter turn and finished only in the corresponding Gardena. Gone is the annoying attachment of hose clamps or screw connectors. The Gardena products are not cheap, but the ease of use and quick installation by your good value for money.
