Here's my Pump with a jubilee clip:
And heres my Block with the swiftech hoselocks:
They are both extremely sturdy. Though the Swiftech locks look more attractive. Though I would trust the Jubilee clip over the plastic locks. Though thats just because its metal over plastic. The plastic would theoretically fail over the the jubille, due to the fact you can slide the teeth up and down, so I guess with a knock or some vibration the could come loose.
But im sure the rubber like Tygon will prevent that with the grip it gives.

If you are using 1/2", you need to use clamps of some sort, not zip ties. The clamps I recommend over and over are the "Type 430 Stainless Steel Nonperforated Worm-Drive Hose and Tube Clamps" from Mcmaster, part #
5076K13 on page 239. They don't cut into the tubing, they are 3/8" wide so they fit onto barbs perfectly, you can tighten them down with a ratchet, and they last forever. I have been reusing the same ones in several builds and modifications over the course of 2 years now.

I normaly use the metal ones even though they aren't as nice looking, however i've used zipties with no issues as well, you just need to make sure you use a pair of pliers (needlenose works best) to tighten them as simply doing it by hand really isn't enough, just zip them by hand as tight as you can then take the needlenose pliers and grab it right where it comes out of the zip part and twist the pliers.
the bottom two pics would be the best, most obviously because they use them on cars, cars get hot, and generally last quite a long time, being metal they will not break, being stainless they will not rust, and tighten alot. i use the worm drive ones as they are reusable, the other type is not, may not look as nice? will never leak if correctly put on

I have always used zip-ties with no leaks for about 7 years and countless loops. I place one in alternating directions between each barb on all hose connections.
Some say not to use them on 1/2" fittings (I'm assuming with 1/8" wall due to overall thickness). I have used them on 3/8" and 1/2", both 1/8" wall. All Tygon 3603, and some on specialty Tygon (5000'something). I use needle nose pliers or a zip-tightener tool to make sure the ties are tight. I have even used a single zip tie on a slip fit over an Eheim pump outlet (1/2" tubing) with no issues.
Just make sure they're tight and doubled up if you can (or just if you're paranoid).

This is a picture of the smooth clamps mentioned above. Kinda hard to see, not sure if this image will help anything out.
7329K13 WIDE-BAND SELF-TIGHTENING SPRING HOSE CLAMP, FOR 3/4" HOSE OD from mcmaster
Both work very well much better than any plastic clamp or zip ties. Ever since i started using the Spring clamps i have been hooked they work great and I don't plan on switching to anything different. I have tried all the other options and the spring clamps are my favorite.

stainless steel worm clamps. I installed them on my system 4 years ago... its been running 24/7 with no issues what so ever.
I hate those pinch clamps... those things are so hard to work with in my engine bay so... I dont even touch those...
BTW, this is my first post in like 4 years hahaha. check out my rig I made 4 years ago in my sig hahahahaha.

This should have been a poll. I asked a similar question a while ago and the consensus was something is better than nothing.
If you buy worm gears... don't overtighten as they can oval and POSSIBLY cause a leak. But, by overtightening I mean putting the hurt on it, haha.
If you buy plastic clamps (AKA Swiftech clamps) make sure they are tight and of the right size as they don't have very good range.
Zip ties... well they look nice and will probably hold fine but I don't know if I could trust them. But, MANY MANY people do and have had very good results. Again... make sure they are tight and of good quality so that they will hold and not pop when you tighten them hard.
Metal Spring Clamps, they should hold fine but they can leave a heck of an imprint in the tubing. I have never used these.
My personal choice, Worm gear clamps, see Project in sig for more info.

Have used both worm gear and plastic type. Both work fine. Boils down to personal preference in the end.
If we're gonna do a poll, there'd better be an option for no clamps at all. I've got all 7/16" tubing on 1/2" barbs (two rads, two water blocks, one pump, 10 total connections). They are a PITA to install, but even more of a PITA to remove, I usually have to cut them off with an exacto knife.

I'd be very careful not using any clamps... pressure builds up over time. When I was testing my loop (in sig), i ran no clamps and many a hose blew off - water everywhere. Not smart to run no clamps at all.Maviryk said:
