9. A livestock enclosure comprising at least one stall (L) delimited by:
two lateral partitions (L1),
a stall rear sill (L2), extending along an access corridor,
a front limit (L3), forming the back of the stall (L),
wherein said front limit (L3) includes a flexible tubular device (1) to form a lower stop, the flexible tubular device comprising a single-piece part (1) having a tubular wall (2) that delimits a sealed chamber (3) intended to be filled with a fluid,
wherein said tubular wall (2) comprises an elastomeric matrix (7) into which is integrated at least one reinforcement ply (8) delimited by two longitudinal portions (82),
wherein said at least one reinforcement ply (8) has the general shape of a sleeve that extends within said tubular wall (2) to surround said sealed chamber (3),
wherein said two longitudinal portions (82) of said at least one reinforcement ply (8) are juxtaposed to each other,
wherein the single-piece part (1) includes a radial longitudinal lip (5), longitudinally connected to the tubular wall (2),
wherein the two longitudinal portions (82) of said at least one reinforcement ply (8) are superimposed to each other within said radial longitudinal lip (5), and
wherein said at least one flexible tubular device (1) is fastened through fastening means (57) added through the radial longitudinal lip (5).
