Fitting made from two planar fitting halves (1a, 1b), for connecting two components (2a, 2b), screwed to the counterform interlocking fitting halves (1a, 1b). On a relative longitudinal displacement of the components (2a, 2b), a locking clip (7), held on the fitting half (1b) in a first housing recess (8), by means of a fixing screw (7), folds in the transverse axis and, with a second housing recess (10), surrounds a head (13) of a fixing screw (14), fixed to the other fitting half (1b). The above reliably prevents a detachment of the connection in all directions.
