Just disconnect an create a coil of hose in loops in direction it naturally coils, as delivered, hold together with string, or old laces or whatever. Do not wrap around between hand and elbow that leads to a mess. Also note most if not all garden hose connectors work together, eg Gardens with Hoselock. **Q: Will it join 2 female 3/4 inch connectors?** A: Hello, this conector is for the transition from 19 mm (3/4") to 13 mm (1/2") hoses. Best regards GARDENA Service **Q: It's battery powered?** A: Hello, no, it´s not.

Clicks into place easily. There are no leaks. Would have been better if it is made from brass rather than plastic-not quite so sure it will will survive a proper hose twisting/bending ## Frequently Bought Together - Gardena 02931-20 Extension Joint - Grey - Gardena Hose Connector 13 mm (1/2 inch) and 15 mm (5/8 inch): Connectors for The Hose Start, Grip Wells, Easy Installation, Packed (18215-20) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.nl/products/66401362-coupling-connection-piece-for-secure-hose-connection-connection-of-two](https://www.desertcart.nl/products/66401362-coupling-connection-piece-for-secure-hose-connection-connection-of-two) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-05-27*
