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 do exactly what they say they will. They are also super cheap for what they are. I like having the cable clip on them as well. They don't work great on super shielded thick cables, but I have only come across one cable that has given me an issue with popping out of the little clip. I have them on 3 guitars that always have straps and am planning on buying even more for the rest of my guitars. As far as the security of the strap goes, I haven't knocked one off yet, and I am rough with my guitars.

I like these locks for my guitar straps. Keep my guitar sitting on my shoulder and not worry about it hitting the floor if the strap came off. A good investment and will buy more.

Customer service was great.I only got one in my first order.They sent me another pair next day.Now, I wouldn't try flinging a 2k les paul around with them. But for in home practice, they be just fine.

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

hey they work. keeps my strap on the guitar and I'm not constantly worrying about it coming off. no complaints here.

Simple effective

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.

Unfortunately the clip is too small to attach on “over sized” strap buttons. Like some PRS, Warmoth or Gotah buttons. Bought one for giggles, was curious about strap holder feature.
