Wire duct with a weakened and readily deformable wall for displacing wires held within

A protector for accommodating cables therein, comprising an elongated tubular body (1;101;201;301) having opposed side walls of a selected rigidity extending continuously along said tubular body, said tubular body further having a top wall and an opposed bottom wall (5;105:205:305) extending between and connecting said side walls, said bottom wall having at least one weakened portion (7;107;207;307) such that said bottom wall (5;105;205;305) is less rigid than said opposed side walls and is configured to be deformed outwardly in response to deformation of said side walls toward one another for permitting a displacing of the cables away from said side walls and thereby preventing damage to said cables due to the deformation of said side walls.
