forked at the end of the two portion part of the lower strut 7 the mounting support 5 is shaped as shown in fig1 8 the upper strut 4 passes from the guidance element 3 to the mounting support 5 without any gap but thereagain an edge 17 can create space for the insertion of the holding head 6 the adjusting device 10 can be adjusted once and for all following the installation of the shower holder if a readjustment proves necessary in the course of the this can also be brought about with the aid of a screwdriver fig1 shows an embodiment where the interior of the casing of the guidance element 3 contains a tube 18 extending over substantially the entire length of the element 3 on the side of the tube 18 facing the mounting support 5 an upwardly and downwardly extending tongue spring 19 is fixed thereto the spring 19 can engage with its slightly downwardly bent ends 20 against a correspondingly shaped inner shoulder of the shower holder this leads to action of the shower holder at right angles to the direction of the wall rod 1 which leads to a non positive fixing of said holder it is possible by a choice of spring to ensure that only a limited force is necessary for displacement purposes fig1 shows an embodiment in which the non positive fixing also takes place through a strip 21 a pushbutton 23 is pivotably connected by means of a spindle 22 traversing the casing of the guidance element 3 the pushbutton 23 is located.
