Abstract: A packing structure for protecting a cylindrical object includes an integrated fastener, the packing structure assuming the form of a collar hooping the object to be protected and being characterized in that the collar includes over at least a large portion of its periphery at least one at least partly closed housing (4) which is designed to receive and retain on the collar the fastener (2) which shall enclose and tighten the collar, the housing being a channel fitted with two lips, the fastener (2) being inserted between these lips. In the packing structure for protecting the end of a cylindrical object, the collar is fitted with a substantially right-angle flange (5) covering the end segment of the object to be protected.

Abstract: The invention relates to a packing structure protecting a cylindrical object and comprising an integrated fastener, said packing structure assuming the form of a collar hooping the object to be protected and being characterized in that said collar comprises over at least a large portion of its periphery at least one at least partly closed housing (4) which is designed to receive and retain on the collar said fastener (2) which shall enclose and tighten said collar, said housing illustratively being a channel fitted with two lips, said fastener (2) being inserted between these lips.

Abstract: The blank has a rectangular body (1) which becomes the skirt of the cap when in use, with complementary fastening means (2, 3), a first fold groove (7) along one edge followed by a strip (5), a further fold groove (8) and a plurality of tongues (6), cutout slots (9) running from the first fold groove (7) to give each tongue (6) an edge which terminates in a truncated point (11A) which fastens in the in-use position to the adjacent edge of the adjacent tongue in order to protect the inside face of a pipe.
