Abstract: A hook device (2) for hanging objects such as picture frames comprises a housing (10) which has an internal space for allowing a carrier for the hook device (2) to extend through the housing (10), and which is normally provided with a projection designed for functioning as a hanging hook. The hook device (2) further comprises a clamping mechanism for fixing the housing (10) on a carrier, wherein the clamping mechanism comprises a first hollow cylinder (20) having a tapered inner surface (21), which is retained in the housing (10) in an axial direction by form closure. During the assembling process of the hook device (2), the first hollow cylinder (20) is inserted into the housing (10) by moving the cylinder (20) through an opening (17) in a radial direction, different from other elements (30, 40, 50) of the hook device (2), which are moved in an axial direction.
