Abstract: The attachment plate has a rectangular planar front wall (2) with two groups (3) each with three mounting sites (3a-3c). These groups are used for mounting sanitary fixtures such as for example isolating valves and the like. The two groups (3) have in each instance two mounting sites (3b, 3c) disposed on a straight line (A). Each group (3) has moreover at least one third mounting site (3a) at a distance (Y) one from the other which is different from the distances (X, Z) of the remaining mounting sites (3b, 3c). The mounting sites (3a-3c) are disposed in such a manner on the attachment (1) that all commonly used sanitary fixtures and the like can be mounted.

Abstract: The attachment plate has laterally several openings (4) which each extend along an edge (9) and around it. The openings (4) serve in each instance the purpose of inserting a rotary snap-in connector (15) which has a handle (17) and a head (16) formed on it. The head (16) is so shaped as to correspond to a dovetail groove (11) of a profile rod (10) and is snapped into it. A snapping lug (7) engages form-fittingly with a channel (12) of a contour of the rods (10). The rotary snap-in connectors (15) can be set in without tools, are latchable and permit an independent mounting of the attachment plate (1) on a supporting frame having profile rods (10).

Abstract: The connection has a connection piece (1) which has two displaceable wedges (4, 13) in a bearing housing (8) . These wedges (4, 13) can be displaced in the bearing housing (8) independently of one another by a guide bearing (15, 16). In the working position, the wedge (4) extends into a dovetailed longitudinal groove (20) of a sectional bar (2). The front side (5) of the wedge (4) is profiled and engages a correspondingly profiled wall (22) of the sectional bar (2) in a positive-locking manner. The wedge (4) spreads two clamping tongues of the bearing housing (8) against the flanks of the longitudinal groove (20). By pivoting the guide bearing (15), the wedge (4) can be retracted, and the connection can be separated. A second wedge (13) is inserted axially into the interior space of a second profiled piece (3). This wedge (13) spreads two brackets (11) of the bearing housing (8 ). Both sectional bars (2, 3) have the same design and may be cut off to any desired length.
