82 k is designed with a preferably conically tapering tip 110 k the tip 10 k engages in the other longitudinal groove 48 k of the guide rail 12 k abutting its conical tip 110 k against an edge 112 k of the longitudinal groove if the straining screw 82 k is screwed farther into the longitudinal groove 48 k the screw axis a of the straining screw 82 k in the illustration according to fig1 moves downwards and pulls with it the free end 84 k of the clamp strap 80 k as a result of this movement the clamping effect of the bulge 90 k of the clamp strap 80 k on the cover band 24 k and the guide rail 12 k is intensified the linear guide arrangement 101 according to fig1 differs from the linear guide arrangement 10 k according to fig1 only in that it dispenses with a specially designed straining screw with a conical tip and accomplishes the same effect with a conventional straining screw 821 the screw axis a of which cuts the plane e of the cover and 241 at an oblique angle the straining screw 821 is screwed into a taphole 981 formed in the vicinity of the free end 841 of the clamp strap 801 of the band securing element 321 and is engaged with its conventionally designed tip 1101 an edge 1121 in a longitudinal groove 481 of the guide rail 121 the other free end 861 of the clamp strap 801 which engages in the other longitudinal groove 481 of the guide rail 121 serves as abutment for the clamping engagement of the bulge 901 with the cover band 241 and.
