An improved apparatus for applying surgical fasteners to body tissue comprising a cartridge containing a plurality of fasteners, an anvil positioned opposite the cartridge, and a locking mechanism to prevent re-approximation of the cartridge towards the anvil when the cartridge is withdrawn from the anvil after the fasteners are fired. The locking mechanism comprises a leaf spring clip with a distal hook for engaging a slot on the anvil support arm. The clip is moved distally when the staples are fired, and the hook engages the slot when the fastener holding cartridge is moved to the open position to release the body tissue.
