You can buy Permanent Mains Flex Connectors that don't involve
plugs and sockets, eg

"Waterproof" versions are also available, for outdoor use.


These are frowned on in many jurisdictions, however if they are
approved in the UK then they can be used there.


Whats the problem with them? Ours all have cord grips.


In the UK portable equipment has to be provided with a fitted plug
- in recognition of the fact that many people were incapable of
correctly fitting (and fusing) one themselves.

So, what are the chances that one of those will correctly choose
and wire one of the above? Or use a non-rugged one outdoors, drag
it around corners, let it fall into a bucket of water, etc?

Many (most?) do not have anything to limit the bending radius of
the cables at the point of entry close to the fixed cord grip. So
strands of the cores break, leading to the risk of fire, failure,
etc.

Few are vapour-tight or even water-tight. As the are often dragged
around through damp grass, left in the shed, etc - there is a real
risk of corrosion..

Bear in mind that a typical application is to "repair" an electric
garden tool - where the user has cut the cable...


Replacing the two cables with a single, contiguous, one is by far
the best solution.


It is the best but sometimes it is too long a job to open up the
appliance and to attach the new flex cores because of the way user-
unfriendly way in which the appliance has been designed.


Make the join at the end near to the appliance so it's not dragged
around corners all the time.
