D'Addario Dual-Lock Guitar Strap Lock - Guitar Strap Locks Set - Protect Your Instrument with No Modifications or Hardware - Secures Cables - Easy to Attach - 1 Pair,Black

These work fast and the cable holder is really worth it for convenience. It's not a complete LOCKDOWN for your guitar strap and if you really pull hard (I mean very hard) it will come of the button. BUT, these go on really fast and simple and come off easily ONLY when you want them to (not by accident).The cord handler is a really handy thing to have. I use it with almost any size cord and my wireless guitar cord from the transmitter which I clip to the guitar strap. Works great!These are super hard yet stiff flexible clip for a super price. Getting them on and off is a 3 minute learned curve. You'll be amazed no one else thought of this. I did NOT have to change my guitar Buttons at all. I use a leather strap that's not super thick but it still fits nice and tight and does NOT slip off the guitar. Hope yours work as well as mine. I have also used one in front / top of my guitar for my headphone wire - it's also VERY handy and more organized when needed.

I've used other strap locks in the past, both for acoustic and electric guitars. Some good, many others not so much.I didn't really expect much from these given the inexpensive price.Admittedly, I incorrectly assumed that these would be metal; some sort of spring steel. I was shocked when they arrived and I saw that they were completely made of plastic. However, they appear to be very durable, and quite springy.My issue is always the same: I use a wide, thick suede strap on my guitar (in this case an acoustic). I have had issues over the past with the strap suddenly deciding to pop off. It seems that the older any leather strap gets, the more likely this is to happen.So using these strap locks I immediately noticed how incredibly easy it was to put onto the endpin, over the strap. At first I was concerned about snapping the unit in half (it is plastic, after all), but that never happened. Instead it slid on smoothly, locking in a shockingly secure position. Once installed the strap lock is literally locked over the endpin, and unable to slip off on it's own.My only concern here is that the endpin doesn't work itself free, since it's just a tapered pin, sort of an "interference fit".So far this hasn't happened.I honestly feel that to date this is the superior design when it comes to strap locks. It's quite clever, and quite a minimalist design.I recommend it.

Great option. Very effective step lock with the bonus that you can route your cable through it and take all tension off the guitar cable jack.

Affordable and easy to use.Don't know if I trust as much as other brand strap locks

Works great. I feel more comfortable about having my guitar hanging on my shoulders without it falling. Seems to be locked in place pretty well. Just know if you have thicker straps it may be harder to put the lock on. Had a hard time with one of my guitars. Hope this helps.

These are certainly larger than the simple rubber washer style strap lock, but these guitar strap locks feel very sturdy and secure. I'm using these to hold a leather strap on a Yamaha 4-string bass. Once you understand how they work, they click on/off easily. As an added bonus, they will also hold the guitar cable securely and keep tension off the guitar's cable jack. I am using a thicker tweed-covered cable so it's a tight fit but it seems to work...probably best suited for standard thickness cables though.

These are great at locking a strap in place, but it is difficult to attach the cable. For thinner cables it is okay, but for thicker cables it takes a lot of fiddling to mash it into the holder. It is much quicker and easier to just loop the cable through the strap.

They're pretty awesome and cheap !I jumped a bunch with them and they wouldn't snap !
