1/2 Inch Perma-Loc x 3/4 Inch Female Hose Swivel.
Do not require any glue or clamps to connect to hose. These fittings are the easiest to use- recommended if you have arthritis or less than macho strength in your hands. Also, these are easy to remove from hose for rearranging or reuse. Insert hose and spin fitting tight. Rovides very positive seal. The 600 series fits 18mm drip hose and 1/2" dripperline.

Perma-loc drip irrigation fittings are the best!
So much easier to use than the pressure fittings.
They can be re-arranged without cutting the line, too.

Stays in place on the poly hose for at least a year or two under constant pressure, in my experience. Goes on the poly tube very rapidly, but once on you cannot get it off again.
