A pushrod-to-bellcrank attachment includes a primary pivot connection and two secondary pin and slot connections so arranged relative to each other that there is a continuing operative connection of the pushrod to the bellcrank in the event the primary connection is lost by small arms fire. When the primary pivot is lost, the pins of the secondary connections act in conjunction with the slots, which are arcuate, as a large bearing struck about the primary pivot to maintain the rod and the bellcrank in their original relative positions about the primary pivot with no introduction of lost motion between bellcrank and rod.
