It means what it says. You do need to close() connections, as there is a finite number available. (The number depends on your unstated version of R, but is at least 50.)

1. closeAllConnections() will close all open connections so
con <- textConnection(Line)
closeAllConnection()
# now there are no open connections left
2. close() will close an individual connection:
con <- textConnection(Line)
scan(con, what = "")
close(con)
3. strsplit will split your line without using connections
strsplit(gsub(" +", " ", Line), " ")
3a. This is the shorter for the case that there is exactly one space
between words:
strsplit(Line, " ")
