Abstract: A separable, form-fitting joint (5) is proposed in which one plastic component is designed as a base component (6) and another component, a cover (7), is designed as a component to be mounted on the base component (6), and the cover (7) is equipped, as viewed from the mounting direction (10), with opposing pocket-shaped receptacles (13, 14, 20, 21) which are formed on cover (7) by tongues (16, 17, 22, 23) on the cover (7) and which accommodate the insertion of flange-shaped edge sections (9, 12) of the base component (6).

Abstract: The bumpers of motor vehicles nowadays are being used to an increasing extent to carry components of small size in which their position on a bumper is especially advantageous for their operation due to its exposed location. For example, it is known to build into the bumpers of vehicles flashers, parking lights and especially distance sensors (parktronic sensors, abbreviated PTS) which detect the distance from other vehicles or obstructions and are designed as parking aids. The components must be mounted such that when the bumpers are affected, especially by mechanical shock, any loosening or dropping out will be impossible. At the same time the mountings must be able to be made simply and inexpensively. It is therefore proposed according to the invention that the tongues be affixed by feet to the bumper, or in case of a bumper of modular design, to one of its modules, and be positioned opposite the opening.
