ABSTRACT:
A device for welding plastic tubes includes a laterally movable tube holder having tube holding areas and a laterally fixed tube holder having tube holding areas. Each tube holder includes clamping structure for clamping each tube placed in the respective tube holder areas and for creating a fluid free area. A spring mechanism urges the laterally movable tube holder toward the laterally fixed tube holder to maintain the clamp faces flush against each other. A clamp locking mechanism is provided to supplement the action of the spring mechanism by maintaining the clamp faces flush against each other during the loading of the tubes.
