A surgical fastener is provided which is adapted to be secured in a closed position about body tissue by a fastener-applying instrument. The surgical fastener comprises first and second leg members, each having distal and proximal ends. A resilient hinge connects the first and second leg members at their proximal ends. A latch mechanism is associated with the distal ends of the first and second leg members for locking the first and second leg members in a closed position about the body tissue. Lateral extensions are provided on the first and second leg members for engaging with the fastener-applying instrument to allow the instrument to move the first and second leg members toward one another until the latch mechanism locks the first and second leg members in a closed position about the body tissue. The first leg member and its associated lateral extensions and the second leg member and its associated lateral extensions may each define a substantially T-shaped, trapezoidal or bell-shaped cross section.
