A plug mounting (50) is provided as a combination of a plug (10) and a mount (30), for the detachable mounting of an equipment part, such as an inner panel, to a supporting frame, such as an aircraft fuselage. The plug (10) has a mounting pin (12), which has an annular groove (25) on one end, which can be engaged with a slide (34) of the mount (30), which is under spring pretension. The mounting pin (12) can be connected to the foundation by a damping element. The mount (30) is fastened to the housing (32) on the equipment part. The mount (30) has an eccentric lever (42) for unlocking the plug (10) by displacing the slide (34) against the spring pretension. The arrangement is made so that only the mounting pin (12) of the plug (10) needs to be inserted into the opening of the housing of the mount (30). It is not important whether an opening in the slide (34), into which the mounting pin (12) is to be inserted, is precisely aligned therewith, because the slide (34) is pushed against the spring pretension by one end of the mounting pin (12), wherein the spring pretension subsequently ensures that the slide (34) is latched in the annular grove of the mounting pin.
