About Splices
You can splice wires together using the splice function. You can create two kinds of splices:
Butt splices—the wire is split into two separate wires and a one-pin component (the butt splice) is placed at the point of separation.
Through splices—the one-pin component (the through splice) is placed on the wire without splitting the wire. Additional wires can then be routed to the splice.
 
* Before you create a splice, you must create a symbol with a single node.
When you create or move a splice, note that:
A butt splice splits the wire it is placed on into two separate wires and does not move when the wire it is placed on is moved.
A through splice does not split the wire it is placed on and moves with it.
 
* A component or connector that is being placed can also be inserted into an existing wire as a splice.
