Abstract
The present invention relates to a device for fixing a spring to a spacing grid for fuel elements of nuclear reactors. This device is characterized in that it is constituted by two retaining bridges (8) for the spring (6) made in one of the thin metal sheets constituting the grid and maintaining the spring (6) against said sheet. Two other bridges (10) located outside the bridges (8) constitute abutments for stopping the translation of the spring (6). A double stamping (12) made in the thin metal sheet at the approaches of each retaining bridge (8) constitute a precise translation guide for the spring (6). Application to the spacing grids of fuel elements of nuclear reactors.
