The frame, which is obtained by assembling two struts (21) with two cross-bars (22) each of which is provided with a heald-carrier rod (29), comprises at least one hoop (40) surrounding a tubular extremity (28) of said cross-bar (22) in an area in which it is joined to the adjacent strut (21) and an area in which at least one locking member (25,26) of part (21a) of said strut is received. The area of junction is created in part (35) of the extremity (28) provided with an external transversal profile which is essentially convex. The hoop is provided in order to resist a locking effort (F3, F'3) exerted by the locking member (23, 24). |
