Fitting for connecting two parts (20, 30), comprising a cup-shaped housing for insertion into an open-edge bore in the one part, two double-armed levers (5, 6) which are connected in an articulated manner about an axis running, in the housing, parallel to the cup axis and which each have an inner lever arm (5a, 6a) which is arranged in the housing and an outer lever arm (5b, 6b) which projects outwards beyond the circumference of the housing for engaging in a surface-area bore in the other part, and a handle which can be moved from a starting position into an end position and has an actuating element for rotating the inner lever arms (5a, 6a) in relation to one another such that the two outer lever arms (5b, 6b) are spread further apart in the end position of the handle than in the starting position, wherein the handle is formed as a pivot lever which is mounted on the housing so as to be rotatable from the starting position into the end position and is formed to be double-armed and is mounted on the housing so as to be rotatable about an axis parallel to the rotational axis of the two levers (5, 6), characterized in that the two double-armed levers (5, 6) are either connected together in a scissors-like manner and the actuating element cooperates with the inner faces of the inner lever arms (5a, 6a), which face one another, in order to spread the two inner lever arms (5a, 6a) further apart in the end position of the handle than in the starting position, or are connected together in the manner of spreading tongs and the actuating element cooperates with the outer faces of the inner lever arms (5a, 6a), which face away from one another, in order to press the two inner lever arms (5a, 6a) further together in the end position of the handle than in the starting position. a cup-shaped housing for insertion into an open-edge bore in the one part, two double-armed levers (5, 6) which are connected in an articulated manner about an axis running, in the housing, parallel to the cup axis and which each have an inner lever arm (5a, 6a) which is arranged in the housing and an outer lever arm (5b, 6b) which projects outwards beyond the circumference of the housing for engaging in a surface-area bore in the other part, and a handle which can be moved from a starting position into an end position and has an actuating element for rotating the inner lever arms (5a, 6a) in relation to one another such that the two outer lever arms (5b, 6b) are spread further apart in the end position of the handle than in the starting position, wherein the handle is formed as a pivot lever which is mounted on the housing so as to be rotatable from the starting position into the end position and is formed to be double-armed and is mounted on the housing so as to be rotatable about an axis parallel to the rotational axis of the two levers (5, 6), characterized in that the two double-armed levers (5, 6) are either connected together in a scissors-like manner and the actuating element cooperates with the inner faces of the inner lever arms (5a, 6a), which face one another, in order to spread the two inner lever arms (5a, 6a) further apart in the end position of the handle than in the starting position, or are connected together in the manner of spreading tongs and the actuating element cooperates with the outer faces of the inner lever arms (5a, 6a), which face away from one another, in order to press the two inner lever arms (5a, 6a) further together in the end position of the handle than in the starting position.
