The old, all-plastic ones probably did not.  The newer ones with springy 
metal
coil inside and the "ears" for tightening them are supposed to do so.

Lamp sockets are all screw-clamp.  Plugs have a variety of versions, 
including some
with "vampire" teeth that pierce the zip-cord to make contact.  I always 
worry about
high-resistance faults that don't blow the breaker.  I like the British 
idea with the
fuse in the plug, so you can set the fuse just a little higher than the 
appliance needs
to draw.  I haven't found any hardware in the US to allow this except in 
Christmas
tree light sets.
