Hi I need to join two cables I’d like to do it under the floor so maintenance free would’ve best but I could do it in a conduit terminal box on the outside wall. What connectors would people recommend
MF is challenging. Screw terminals, even in a jell filled box, probably aren't going to suffice for that. Even crimps in an adaptable box still means the connection to the armour isn't strictly speaking MF - as both the armour-gland and gland-box connections are basically still a threaded screw/nut arrangement. (But might not be an issue in practice if the armour isn't being relied upon as a protective conductor and the gland at the other end is accessible.)
So if it really can't be accessible, I'd probably also go for a resin encapsulated one (e.g. https://www.tlc-direct.co.uk/Products/SWJK2.html) - I would think that a few turns of tape around T&E where it enters the shell should suffice to stop the resin leaking out until it sets. Even then you might need a little extra ingenuity to interconnect the amour, 10mm² core, 4mm² c.p.c. from the T&E and 10mm² bond (might be easier to connect the T&E's c.p.c to the armour and the 3rd core to the 10mm² G/Y and join at the far end).
