Patent ID: 7779995

Claim:
Connector arrangement for connecting the ends of a web, comprising: two elongate elements, each elongate element having a longitudinal direction parallel to the edge of one of the web ends and a transverse direction perpendicular to the longitudinal direction, at least one elongate leg for fastening on one of the web ends, and a longitudinal flank which is directed away from the web end, wherein for connecting the web ends, the elongate elements are oriented with their flanks in engagement and their elongate legs extending in opposite directions, wherein each longitudinal flank has a first contour extending in the longitudinal direction of the elongate elements in a first longitudinal-section plane substantially parallel to a plane defined by the longitudinal and transverse directions of the at least one elongate leg, wherein the first contour is configured so that the first contour of one elongate element engages in a corresponding first contour of the other elongate element respectively, wherein each longitudinal flank has second and third contours in second and third longitudinal-section planes, respectively, extending parallel to the first longitudinal-section plane, wherein the second and third contours are different from the first contour and are configured so that the second and third contours of one elongate element engage in a form-fitting manner in third and second contours, respectively, of the other elongate element, and wherein the first and third contours together of each longitudinal flank form tongues and the second and third contours together of each longitudinal flank form grooves in at least one cross-section plane extending perpendicular to the longitudinal direction, wherein the tongues and the grooves of each longitudinal flank alternate, and wherein the alternating tongues and grooves of one elongate element engage the alternating grooves and tongues respectively, of the other elongate element to form tongue-and-groove joints.
