Look in the end of the wire side of the snap, notice the two little wires on
the inside of the snap. They should look like this. If one or both are missing,
order a replacement set. If they look ok go to the next picture below.
The way we can increase the connection tension is to slightly
"oval" the snap side with a pair of pliers.
After you squeeze the little "outie" changing the shape to a slight
oval shape, re-engage the snap and rotate it slightly until it is a little
tighter. Your connection is now better.
