In a suction disc mounting arrangement for supporting objects on smooth surfaces wherein a suction disc is supported in a housing cavity in which also an operating element is movably disposed and connected to the suction disc and operating means are supported on the operating element for pulling the suction disc into the housing cavity, a compression spring element is disposed in the housing behind the operating element in a housing sleeve so as to bias the operating element and together therewith the suction disc outwardly from the housing and into contact with a smooth surface when the disc mounting arrangement is disposed on such smooth surface for creating a relatively high vacuum, when, upon actuation of the operating element, the suction disc is pulled into the housing cavity.
