The valve comprises a tube (4) made from deformable material and fixed to a tube (1) made from rigid material. The inside of the deformable tube (4) contains a tapered closure member (5), the tip (6) of which points towards the rigid tube (1) and has an incision (7) which penetrates right through its wall. The outside of the deformable tube (4) has two plane surfaces placed perpendicular to the axis of the incision (7) so that a pressure exerted on the plane surfaces causes the closure to deform and, on account of the incision (7), a clamp (10) grips the deformable tube (4) against the rigid tube (1). The valve is used in tubes containing cosmetic products, foodstuffs or epoxy adhesives. <IMAGE>
