Click into place, then lock the collar
This black-and-orange female garden hose connector adds a twist lock to a matching quick-connect coupling. A separate soft-grip nut secures the connector to the hose.
For nominal ½-inch to ¾-inch garden hose. One connector supplied; hose and mating fittings are separate.


The locking collar belongs at the quick-connect end
The socket connects to a matching male garden quick-connect plug. Push it fully into place, then follow the padlock markings on the collar to lock the coupling.
This locking action is separate from tightening the hose nut. It helps guard against an accidental release of the coupling; it does not remove the need for a correctly fitted hose and a sound mating seal.
To disconnect, turn off the tap and release remaining pressure first. Move the collar to the unlocked position before operating the quick-release coupling.
The tap and male fitting in the connection guide illustrate the operation and are not included.

A separate nut grips the hose
The rear nut and hose-gripping section hold the hose onto the connector. The fluted black outer surface gives you a grip when tightening by hand.
Check that the hose is within the nominal ½-inch to ¾-inch garden range and that its wall thickness suits the fitting. Seat the hose fully and tighten the nut by hand. An old, distorted or split hose end can prevent a good connection.
This is a hose-end fitting, not a reducer for joining two bare pipe sizes. The female quick-connect socket at the other end still needs a suitable male garden plug.
Check both sides of the connection
Hose fit and quick-connect fit are separate checks.
At the hose
Check the hose size, wall and end condition. Make sure it is seated securely and the nut is hand-tight; avoid using tools to force the plastic nut.
At the male plug
Check the plug type, seal and space around the inlet. Push the socket fully home and use the collar markings to lock it. Check the connection gently before watering.
When putting it away
Shut off the water and release pressure before unlocking. Keep grit out of the socket, inspect the mating seal and drain the hose before storing it protected from frost.
Questions about this lockable connector
Is this one connector or two different size options?
One connector is supplied. It is designed for the stated nominal ½-inch to ¾-inch garden hose range. Check the actual hose and wall thickness when fitting; there is no separate size selection on this page.
Does it screw straight onto a garden tap?
No. The front is a female garden quick-connect socket, not a BSP tap thread. A bare threaded tap needs a suitable male quick-connect tap adapter, which is sold separately.
Does the twist lock tighten the hose nut?
No. The marked collar locks the quick-connect coupling after it has been pushed onto a matching male plug. The rear nut grips the hose and is tightened separately by hand.
Will it fit every pressure washer or watering accessory?
Check the actual inlet or plug first. It needs a compatible male garden quick-connect fitting and sufficient clearance for the collar. A machine with a different inlet needs the correct adapter; this connector does not establish the pressure or temperature suitability of the rest of the setup.
