Got a pond filter hose, irrigation line, or garden hose that you need to extend or repair? This simple Pisces joiner is your fix. It's a straight connector with barbed ends, designed for 20mm internal diameter hose (that's about 0.75 inches). You just push one hose end onto each side of the connector—the barbs grip the inside of the hose to create a tight seal and prevent it from slipping off easily. For maximum security and to prevent leaks under pressure, it's always a good idea to also use a hose clip (worm-drive clamp) over the hose on each side. Made from tough, durable plastic, it's perfect for pond setups, drip irrigation, general garden use, or even some workshop applications. It's a cheap, essential little fitting to have in your toolbox for any DIY plumbing job involving tubing.
