IP68 Waterproof Junction Box Outdoor Cable Connector, Extension Electrical Cable Protector for Cable Diameter Ø5mm-8mm (1 Pack)

So far can't fault them. Straightforward to attach, seem reasonably durable. Used to extend cable to pond pump. Don't think I'd recommend for situations where cable is getting pulled about as strain relief is fairly minimal as you'd expect. However, for joining outdoor cables that stay put such as pond equipment and lighting should be fine. The grommet seals seem ok and should keep moisture out if using proper outdoor cables, don't think I'd risk submerging them though.

I had tried to install a new LED security light but the cable supplied was shorter than the old one and I couldn’t seem to open the cable grip to replace the cable, so had to extended it. So I bodged it with electrical tape until I could install these.The connectors are about as subtle as I have seen and are easy to install. I found I didn’t really need grips or spanners as they can be suitably tightened with fingers. I found getting the wiring length a bit tricky, but after a few goes it’s all nice and sturdy and I don’t have to worry about water ingress - and so much safer. All I used were a pair of wire strippers and a small Philips Srewdriver. Great stuff

I used these to extend my outdoor security lights. Easy to wire up. Wire retaining screws a bit fiddly.

Ideal - nice and compact and well constructed. Ideal to repair my "sliced through" extension cable.

I had to return it because the lead was thinner than the product's diameter, but it was easy to use. You only need a small screwdriver; the product will protect each side from water intrusion. I'd suggest it for kitchen products with broken leads. It's sturdy enough to prolong the life of old appliances.

Brilliant little connection devices at great price

Good product. Easy to fit and has worked well on my outside cable

They do work but when/uf yiu have to remove them ( I.e. over winter) it is difficult identifying what bit to unscrew and I ended up with blue brown and earth connector pins out of their 'permanent' sockets.
