Overview
The Holman 12mm Brass Hose Joiner joins two lengths of 12mm hose together with a secure Grip N Lock fitting on each side. Grip N Lock technology uses a sharp olive with sharp teeth that lock onto the outside of the hose, so the fitting is removable but will not let go of the hose under pressure. The strong positive click connection gives you confidence the join will hold.
Machined from brass, the joiner resists corrosion and suits outdoor and site use. It is the fitting you use when you need to extend a hose run or repair a hose that has been cut, and it gives a connection that does not pop off and does not leak at the join.

Frequently Asked Questions
How do I join two hoses with this fitting?
Slide each end of the joiner onto a 12mm hose end and lock it in place. The sharp olive teeth grip the outside of the hose and hold it firm, so the two hoses are joined end to end with a connection that will not pull apart under water pressure. The join stays solid even when the hose is dragged across the garden or left connected under mains pressure overnight.
Will the joiner leak at the connection?
No. The Grip N Lock design locks the olive onto the hose and seals the join, so there is no leaking at the hose. The strong positive click connection confirms the fitting is properly seated before you turn the water on.
Is the joiner removable?
Yes. Grip N Lock fittings are designed to be removable, which is useful if you need to take a hose run apart for storage or reconfiguration. The fitting comes off when you want it to, but stays locked on the hose during use.
