A shock absorber or vibration damper with a securing element which has a ring area for the axial fixing and securing of ring-shaped components, in particular for securing guide bushings and gaskets for the piston rod of a hydraulic vibration damper. The securing element is characterized by a plurality of projections which project axially to locate and fix the position of a cylindrical body, whereby the projections extend from the ring area, and the projections are bent out of the securing element. The cylindrical body secured by the projections can possibly be the inner tube of a two-tube vibration damper or a decompression stop spring. The invention teaches that the securing element can be used to perform multiple functions in part by securing multiple components.
