The invention relates to a holding device provided with a receiving system for receiving a mobile telephone (30, 30′), said holding device comprising a housing (1). The receiving system is formed by at least two lateral jaws (3) projecting from a rear wall of the housing (1), at least one of said jaws being laterally displaceable and both of said jaws being provided with padding (5) that can be compressed by from lateral housing walls of the mobile telephone (30, 30′). The distance between the jaws (3) can be adjusted to the width of the mobile telephone (30, 30′) by means of an adjusting device (11) provided in the rear wall (2). The adjusted jaws (3) remain fixed for the insertion and the removal of the mobile telephone (30, 30′), and the mobile telephone is fixed in the holder exclusively by means of a friction connection produced between the compressible padding (5, 6) and the mobile telephone (30, 30′). The aim of the invention is to create a universal holding device for different types of mobile telephones (30, 30′). To this end, the adjusting device (11) comprises a rotatably arranged plate (15) that is connected to the two jaws (3), and can be fixed in the rotary position thereof by means of a centrally arranged screw. The screw head (14) can be actuated on the rear wall (2) and covered by the inserted mobile telephone (30, 30′).
