Abstract: A first component with a fixing groove is affixed to a second component, using a ball-head screw having a thread and a ball head, a slot nut for the thread fitting into the fixing groove of the first component, and a fixation part having a ball head seat and a planar fixation support surface for fixing the fixation part to the second component. The ball head seat receives the ball head, forming a ball joint. In a central position, the fixation support surface is parallel and offset to a longitudinal axis of the ball-head screw. The ball-head seat includes recessed portions receiving a screw portion of the ball-head screw. An inclination angle between the longitudinal axis of the ball-head screw in the central position, and the longitudinal axis of the ball-head screw in the position when received in the recessed portion, is at least 90°.

Abstract: A two-piece, flush-mounting box designed for installing plumbing elements consists of the flush-mounting box itself and a flange that may be fastened to the side walls of the flush-mounting box at a certain distance from its front. That distance is preset prior to installation in order that, as the case may be, removal of its protruding portion will be unnecessary or the front surface of the flange will be flush with the front or rear surface of the wall when it has been installed.

Abstract: An arrangement for installing a sanitary fitting contains a concealed tank with passage openings to be fitted in a wall and within which can be fitted a fitting body. The connection between the fitting body and the concealed tank takes place exclusively with the aid of connecting elements made from a soundproofing material and through which pass the passage openings of the concealed tank. There is no direct contact between the concealed tank and the fitting body. Different fittings can be screwed to the fitting body. The connecting elements can be simultaneously used for the passage of water pipes.

Abstract: In a bath rim fitting or other fitting, in which a shower hose extends through a plate or the like and whose back is difficultly accessible, it is proposed to connect the shower hose to the fixed pipe with the aid of a pressure hose. The pressure hose is sufficiently long that it can at least be drawn up to the plate opening by pulling on the shower hose, so that it is possible to replace the latter in front of or outside the plate.
