Abstract:We give a strengthening of the closure concept for claw-free graphs introduced by the second author in 1997. The new closure of a claw-free graph $G$ defined here is uniquely determined and preserves the value of the circumference of $G$. We present an infinite family of graphs with $n$ vertices and $3n/2 -1$ edges for which the new closure is the complete graph $K_n$
