A device for squeezing out a desired quantity of pasty contents from a collapsible tube. Two elongated members connected by a frame are provided with at least one resilient tongue disposed therebetween. The tongue is a U-shaped leaf spring having one side integrally attached to a respective elongated member and-another side being free. An opening is provided between the two tongues (or between the tongue and the other elongated member) with this opening narrowing gradually from a relatively wide entrance through which the sealed end of the tube is inserted to a narrow slot which exerts a pressure on the walls of the tube while the device slides on the tube. A slot, and more particularly the tongue(s) exerts a constant force on the flattened walls of the tube to prevent the contents of the tube from escaping through the slot into that portion of the tube which has been emptied.
