1. A bend restriction element for restricting the bending range of a conduit,
wherein the element is modular for forming a tube segment all around the conduit through locked interlocking circumferential interconnection, i.e., interconnection in circumferential direction of the conduit, of the element with at least one similar such element, wherein said tube segment is modular for forming an articulated tube all around the conduit through locked interlocking longitudinal interconnection, i.e., interconnection in longitudinal direction of the conduit, of said tube segment with at least one similar such tube segment, wherein tube segments of the articulated tube can hinge relative to each other about lines which are transverse to said longitudinal direction of the conduit, and wherein the hinging range of said hinging of the tube segments is restricted for said restricting of the bending range of the conduit, characterized in that the element is configured such that said locking of said circumferential interconnection of the elements of at least one tube segment concerned of the articulated tube is ensured both by the manner of interlocking of the longitudinal interconnection of the tube segment concerned with a tube segment of the articulated tube situated in the longitudinal direction on one side thereof, and by the manner of interlocking of the longitudinal interconnection of the tube segment concerned with a tube segment of the articulated tube situated in the longitudinal direction on the other side thereof, wherein said respective manners of interlocking are also part of, respectively, ensuring said locking of said circumferential interconnection of the elements of the tube segment situated on said one side, and ensuring said locking of said circumferential interconnection of the elements of the tube segment situated on said other side. |
