Having recently had a mad hour cutting open the laptop end plug of my Dell
power supply in order to mend a wire (battery long since dead), I notice
that the rubber sleeve around the power supply end has also worked loose
exposing the braided wire. This will presumably also be giving up the ghost
before long too.

I can't see how the power supply is held together. Anyone know? Are they
all moulded in one go, or is there some hidden way they are held together
that can be released for redoing the lead connections?

Cheers,

S

The two halves are welded together. Usually this is ultrasonic welding.
When repairs are done the halves are solvent welded.

Often appear to be made in two halves bonded together with epoxy adhesive.

My advice is not to attempt to cut it open if it is working.
Instead, tape the cable to the PSU in such a way as to take the strain off
the damaged part where it emerges from the PSU

In similar vein, I recently levered apart the two halves of a dead Sony
PSU quite cleanly. Mixture of clips and welding. Had I to make a similar
repair to yours I'd have either glued and cable tied/taped the case back
together or just bought a big enough box to rehouse the innards at Maplins.

Where are we going and why am I in this handbasket?

Why would you want to rehouse the innards at Maplins?
