Patent ID: 6994499

Claim:
A device for fastening of tubular objects, comprising: a C-shaped mounting rail ( 3 ) having an elongate opening ( 2 ); and a rail nut ( 1 ; 21 ; 31 ) having a width (b 1 ) measured in a direction parallel to a longitudinal extent of the mounting rail ( 3 ), a uniform height (h) measured between extending parallel to each other, axially spaced, upper and lower surfaces ( 1 ′ and 1 ″), and a length (c) measured transverse to a width direction of the rail nut ( 1 ; 21 ; 31 ) and parallel to the cross-sectional plane and which is greater than a width (b 2 ) of the elongate opening ( 2 ), the rail nut width (b 1 ) corresponding at most to the width (b 2 ) of the elongate opening ( 2 ); wherein the rail nut ( 1 ; 21 ; 31 ) is formed of a hollow profile provided with at least two constriction areas ( 13 a, 13 b and 14 a, 14 b ) spaced from each other and defining a through-opening ( 8 ) which is formed by two opposite arcuate sections ( 9 a, 9 b ) of the hollow profile extending between the at least two constriction areas ( 13 a , 13 b and 14 a , 14 b ) parallel to a longitudinal axis of the through-opening ( 8 ) and having respective inner thread sections ( 10 a , 10 b ) for securing therebetween a fastening element having a thread complementary to a thread of the thread sections ( 10 a , 10 b ); and wherein opposite wall sections of the at least two constriction areas ( 13 a , 13 b ; 14 a , 14 b ) are connected with each other.
