A circular stapling device () includes a handle assembly () having an indicator assembly () that includes a clicker assembly () and a biasing member (). The clicker assembly () provides an audible and/or tactile signal to a clinician when an anvil assembly () of the stapling device () is moved from a clamped position towards an open position a distance sufficient to allow an anvil head () of the anvil assembly () to pivot in relation to a reload assembly () of the stapling device () from an operative position to a tilted reduced profile position. The signal is provided to the clinician while the anvil assembly () is locked onto the stapling device ().
