The tube connector crimping tool has a first handle arm joined to a first handle head. A clamp head tongue is joined to the first handle head and clamp head teeth. a gear IS immediately adjacent to the clamp head teeth and joined to a ratchet. A second handle head is joined to the ratchet and a second handle arm. Squeezing the second handle arm toward the first handle arm crimps the first refrigeration tube to the second refrigeration tube.
