I’m fixing my irrigation and there are some cracks that I need to cut out and reconnect them. I have these connections already but being new to irrigation, I’m not sure what to call them. See the attached images for a zoom in and a zoomed out with red highlight.
Home Depot calls them compression couplings. Here is an example.
And if you are looking for the type that go on the inside of the hose, it'll be called a barbed coupling or barbed connector.
You have standard couplings and t’s. since it’s above ground I would guess low pressure drip irrigation. There are tons of brands I just make sure the size is correct and go to a big box store. But Amazon also has them some are called compression, some barbed but coupling is for 1 pipe to another and T is for 3 pieces
