Claim:
A quick-mountable nut capable of at least partially rotation-free, axial displacement relative to a threaded bolt ( 22 ; 52 ), comprising a nut housing ( 2 ; 45 ) having a central through-opening ( 3 ; 47 ); and a springy holding member ( 4 ; 49 ) at least partially located in the nut housing ( 2 ; 45 ) and engaging in at least one screw thread ( 24 ; 54 ), the central through-opening ( 3 ; 47 ) being formed as a tapering radially inward, inner cone ( 9 ; 48 ) for receiving the holding member ( 4 ; 49 ), and the holding member ( 4 ; 49 ) having two, resiliently movable relative to each other, holding sections ( 5 . 1 , 5 . 2 ; 50 . 1 , 50 . 2 , each having a conical section of substantially uniform thickness ( 10 . 1 , 10 . 2 ) abutting a wall of the inner cone ( 9 , 48 ), along at least a portion of an axial extent of the inner cone ( 9 , 48 ), wherein the holding sections ( 5 . 1 , 5 . 2 ) of the holding member ( 4 ) each have an annular middle portion ( 8 . 1 , 8 . 2 ; 51 . 1 , 51 . 2 ) located in a radial plane of the threaded bolt ( 22 ; 52 ) partially engaging along the screw threads ( 24 ; 54 ) of the threaded bolt ( 22 ; 52 ), and wherein the annular middle portion ( 8 . 1 , 8 . 2 ) is formed by an offset extending radially inwardly of the conical section ( 10 . 1 , 10 . 2 ).
