Extending outdoor mains cable for appliances

[Dylan T]

Hi all - I have a couple of power leads for outdoor items that I need to extend to a relocated outside power socket (fountain and lights). Both are mains powered three core .75mm cable and I’m after a simple way to connect more cable that isn’t too bulky as one of them will be visible. Previously ive soldered and covered with waterproof heat shrink (I believe standard isn’t technically water tight) but wondering if there are easier ways that are still slimline. (I’ve used the larger waterproof wago connector gel boxes before but found them a bit of a pain)

Thanks!

Various brands make waterproof flex joiners. Typically they look similar to a short length of conduit with glands on both ends.
