Elastically bendable elongate material with two free ends for stretching an opening edge of an opening of a flexible container. The elongate material, through elastic bending, is brought from a non-use position, in which it is not stretching the opening edge, into an insertion position, in which it is pretensioned and seeks to adopt the non-use position. In the insertion position it is inserted into the opening where it is brought into a use position in which it is pretensioned and seeks to adopt the non-use position such that the opening edge is stretched in a dimensionally stable manner, the free ends of the elongate material are at a distance from each other and between them hold a portion of the opening edge tensioned in a straight line, and a dimensionally stable stretching occurs only in the region of the opening while the rest of the container remains flexible.

A sealing and strain relief device having at least one sealing element is disclosed. The device is arranged in the manner of a sandwich between outer, plate-like bearing elements made from a relatively hard or rigid material and which is made from a relatively soft or elastic material. Slots are introduced both into the outer bearing elements and into the or each central sealing element in such a way that the slots run respectively next to one another and respectively one behind the other, in relation to the sandwich-like arrangement thereof, within the respective bearing element and within the respective sealing element. The strain relief elements are associated with at least one plate-like bearing element such that each data cable, which is sealed and is guided in the region of slots arranged one behind the other of the sandwich-like arrangement, can be restrained using a strain relief element.

A vibration damper for vehicles comprises a work cylinder in which a piston is guided axially by a piston rod. The piston divides the work cylinder into two work spaces filled with damping fluid. A tension stop is provided between the piston and a piston rod guide, wherein a tension stop element including a flexible part and a reinforcing ring is arranged between a support fastened to the piston rod and the piston rod guide. The reinforcing ring limits the deformation of the flexible part of tension stop when subjected to force during operation so that permissible shearing stresses of the flexible part are not exceeded.
