Abstract: Process for closing and cutting into sections a flexible tube, with a cutting element and a pinching closing device for cutting into sections with two cross-sections, each with two parts with indentations that can be placed in removable extension by combination elements and that make a passage with an access, whereby the pinching closing device is in the open or closed state where the cross-sections are closed by locking members and where the surfaces form a pinching closing passage of the tube; the pinching region of the tube is positioned in the indentation of a cross-section; the other cross-section is brought opposite the preceding one and the pinching closing device in the closed state, with cooperation of the locking elements, the tube being positively pinched and closed in two positive pinching zones, and thus held in place; the tube is cut into sections between the parts in the closed state, using the cutting element by passing it into the passage without it interfering with the pinching closing devic

Abstract: The pinching device includes two cross-sections, each having a hollow part with a male indentation and a female indentation, and locking elements, whereby the surfaces of the indentations form a positive pinching passage of the tube; the male indentation has a U shape with a core and two wings; the female indentation has a U shape with a core and two wings; and the pinching passage has a U shape with a core and two wings; the two opposite wings will draw together toward their ends that are opposite to the cores of the indentations, and each of the two wings of the pinching passage has an opening whose width will diminish towards its end that is opposite to the core of the pinching passage; the width of the opening of the pinching passage is at most slightly smaller than twice the thickness of the wall of the flexible tube to be pinched, and, designed to constitute a pinching closing device, it is disposable, performing a function of closing the tube on itself in the pinching region, preventing any passage of
