I was in my local Home Depot last week, searching for some copper pipe
bits to make a bypass for my leaky rear heater. They have a new (to me
at least) product, pre tinned fittings. ( 90 elbows, 45 elbow, T
fittings ) in 1/2" and 3/4" . The interesting bit is, to hold the
tinning solder, each end of the fitting has a raised rib (outside
circumference) that works very well in terms of keeping a hose & clamp
from slipping.

  Have a look. You might be able to rig something up using a T fitting.
