Clip 1 is called a carabiner, great for mountaineering; number two is a boat clip, great for sailing; the third is a butterfly clip which every entomologist should carry. Neither three are good for diving, in fact they are known as suicide clips because they can easily secure you to a line unintentionally; all the line needs to do is press against the jaw and it will open. This does happen; if you have any on your gear, replace them.
The next three are much better. They can only be opened by positive pressure away from the jaws of the clip; these are very unlikely to snag you on a line. Clip number 4 is tempting to make an all metal connection; clip 5 requires a large rotary movement to operate; clip number 6 is the clip of choice and is available in a variety of sizes. In cold water diving, the larger sizes are desirable as they must be operated with 7mm gloves.
