A valve for a plastics tube comprising: a base, having a seat for holding a plastics tube; two side guides, extending from the base and providing a spacing between a top and the seat of the base; a restriction member, for restricting the plastics tube and the restriction member being slideably supported between the side guides, and held in position by the side guides; the top being opposite the base, connectable to the side guides and carrying the restriction member; means on the top for raising and lowering the restriction member onto the seat, one of the side guides being pivotally connected to the top and the other side guide being pivotally connected to the base and connectable to the top serving to secure the side guide in place and limit motion of the top when the other side guide and the top are connected, the top including a bifurcation to accept the side guide and a seat to hold a head of the side guide, the head being stationary with respect to the side guide; and wherein a pressure within the plastics tube presses on the seat and the restriction member such that the head of the side guide is urged into the seat of the top, thereby keeping the valve together.
