Claim:
A connection device for interconnecting first and second tugger carts, comprising: a striker element projecting from the first tugger cart; a connecting arm having a first end operatively connected to the second cart and a hooked terminal end that partially defines a downwardly directed recess for receiving the striker element therein, the first end of the connecting arm being vertically movable and the connecting arm being pivotable between a generally vertical storage position and a generally horizontal locking position; a locking pin operatively connected to the connecting arm and movable between a retracted position for allowing the striker element to be inserted into and removed from the recess and an extended position for maintaining the striker element in the recess, the locking pin including a lower chamfered face engageable with the striker element as the connecting arm is pivoted from the storage position such that the striker element urges the locking pin towards the retracted position and an upper, non-chamfered face for maintaining the striker element in the recess; biasing structure for urging the locking pin towards the extended position; and a handle operatively connected to the connecting arm, the handle pivotable between a non-actuated position wherein the locking pin is free to move between the retracted and the extended positions and an actuated position wherein the locking pin is maintained in the retracted position.
