 the element (A) being made up at one end of its bottom portion by a peg ( 4 ) that becomes inserted in the recess ( 3 ,  3 ′) of the rail (R) and by one or more parts ( 5 ) that become inserted in the interval (B) that extends between two recesses ( 3 ,  3 ′) of the rail (R), the peg ( 4 ) having the shape of a recess; 
 the part ( 5 ) having a rod ( 11 ) passing longitudinally therethrough end passing through the centers of two guides ( 12 ,  12 ′); 
 the rock ( 11 ) being capable of moving longitudinally through the guides ( 12 ,  12 ′) provided at one end with a spring ( 15 ) situated between the part ( 5 ) and the peg ( 4 ); 
 the function of the spring ( 15 ) comprising pushing back the part ( 5 ) becoming inserted in the interval ( 8 ) in order to hold the element (A) in the rail (R) along the axes x-x′ and y-y′; 
 the element (A) becoming released when the rod ( 11 ) is moved in translation in the apposite direction to the working direction of the spring ( 15 ), thereby having the effect of disengaging the part ( 5 ) inserted in the interval ( 8 ) and moving it towards the recesses ( 3 ,  3 ′) in which the part ( 4 ) is inserted, which part can thus be released; 
 the element (B) sliding by means of a groove ( 2 ,  2 ′) on each of its sides receiving the spline ( 1 ,  1 ′) situated on each of the sides of the element (A); 
 the element (B) being provided at one end with a stud ( 6 ) situated at a distance from the peg ( 7 ); 
 the peg ( 7 ) which is retractable is made of a material that can react to a magnet; 
 the peg ( 7 ) being situated in a blind well ( 16 ) that does not open out into the top portion of the element (B); 
 the peg ( 7 ), which is held captive in the well ( 16 ), being capable of moving freely in the base of the well; 
 a spring ( 17 ) being situated between the blind end of the well ( 16 ) and the top portion of the peg ( 7 ) continuously exerting pressure in order to urge the peg ( 7 ) away from the blind end of the well ( 16 ); 
 the peg ( 7 ) projecting from the open end of the well ( 16 ) when it is subjected to pressure from the spring ( 17 ); 
 the peg ( 7 ) projecting from its housing serving to block the element (B) in any recess ( 3 ,  3 ′) of the rail (R); 
 the element (B) being moved by a magnet ( 18 ) being applied and moved in translation so as to raise the peg ( 7 ), extract it from the recess ( 3 ), move it in translation, and place it in another recess ( 3 ′); 
 withdrawal of the magnet ( 18 ) leaving the element (B) blocked in a different position; 
 the presence of the magnet ( 18 ) enabling the element (B) to be moved in translation along another recess; and 
 withdrawal of the magnet ( 18 ) making the rail protection device non-removable. 
 
     
     
         3 . The rail protection device according to  claim 1 , including an element (A) that is stationary relative to the equipment (E) fastened to the rail (R), and secured to an element (B) that is slidable relative to the element (A) via a groove ( 2 ,  2 ′) on each of its sides receiving the spline ( 1 ,  1 ′) situated on each of the sides of the element (A) that covers it in part, is provided with lateral splines ( 1 ,  1 ′) that become inserted in the lateral grooves ( 2 ,  2 ′) of the element (B);
 the element (A) being connected to a piece of equipment (E) by means of a hinge (a 1 ) situated at one of its ends; 
 the element (B) being provided at one of its ends with a stud (b 1 ) that becomes blocked in the piece of equipment (E); 
 the element (A) being provided on its inside face with a centralizer (a 2 ) that, by becoming inserted in the slot (r 1 ) of the rail (R), holds the rail protection device in place in the rail (R) on the y-y′ axis; 
 the element (A) being provided with a shape memory fork (a 3 ) operating on the y-y′ axis and provided with two lugs (a 4 , a 4 ′) that become inserted in notches (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′, b 5 -b 5 ′, b 6 -b 6 ′) at determined positions situated in the inside face of the element (B), each notch (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′, b 5 -b 5 ′, b 6 -b 6 ′) corresponding to a graduation value (c 2 , c 3 , c 4 , c 5 , c 6 ); 
 the shape memory fork (a 3 ) provided with two lips (a 5 -a 5 ′) making it possible, under tine effect of clamping, to move the lugs (a 4 , a 4 ′) towards each other so as to disengage them from the notches (b 2 -b 2 ′, b 3 -b 3 ′, b 4 -b 4 ′, b 5 -b 5 ′, b 6 -b 6 ′) in order to release the element (B), move it in translation to the desired graduation, with release of the lips (a 5 , a 5 ′) enabling the lugs (a 4 -a 4 ′) to be inserted into one of the notches (b 2 -b 2 ′, b 3 -b 3 ′, b 5 -b 5 ′, b 6 -b 6 ′).
