The tube for viscous substances is made from an elastic tube (1) with an outlet (3) at one end and with the other end sealed sealed by gluing or welding. Several connecting elements (5) are located inside the tube and inter-engage during the compression of the tube. The connecting elements are formed by protrusions (6), which are separated from each other, and plug-in points (7) corresponding to them. The protrusions and their plug-in points are located on several straight lines lying horizontally or at an angle to the axis of the tube.
