My clamps of choice these days are made by AWAB. The quality is excellent, I have never once been able to "strip" one and they are far more robust than any of the perforated clamps I've worked with. for hoses 1/2" and larger they are an excellent choice.
There are also plenty of knock offs to the AWAB clamps but they are not all created the same. The AWAB quality is consistent and has proven to me, time and again, the value in them.
