Holding device for pipes

Fastener pipes comprising two complementary parts (5) intended to be assembled, of which, each, has on its assembly face turned towards the other, at least one recess (9) of generally semicylindrical, completing the two corresponding holes of the two parts with a shape corresponding substantially to the outer section of pipe to be clamped between the two parts, each part (5) comprising a body (6) of rigid material having the said at least one cavity (9) whose radius is greater than the outside radius of the pipe (1) that must be held and which is lined with an intermediate shell (11) of elastic material in turn trim inside with a bearing shell (12) rigid material whose internal radius corresponds substantially to the outer radius of the pipe (1), wherein the two bearing shells (11, 12) integral with each other and the body (6), characterized in that the part (5) forming cradle, intended to be supported by the support structure (2), comprising a system preassembly comprising at least one locking element (20) intended to cooperate with at least a hole (21) formed in the structure support, before the final fixing of the two parts, for example with the help of assembly screws (3).
