A snake for installing a cable in a conduit, comprising a body (2, 2', 2'') and a joint (3, 3', 3'') corresponding to the shape of the inner surface of the conduit (8), said body comprising a tubular part (9) which is radially elastic and on which the joint is mounted, and a support part (13, 13', 13'') which is fixed to or integral with the tubular part, the tubular part having a guide surface (14) which is used to guide the snake inside the conduit, the diameter of the guide surface being slightly smaller than the maximum diameter of the joint such that the support part radially deforms the tubular part when the snake passes into deformed parts of the conduit.
(ZH) 一种用于在管道中安装缆索的清管器，其特征在于它包括一个主体(2、2’、2”)和一个设计为沿管道(8)内表面行进的密封件(3、3’、3”)，所述主体包括一个在其上面安装密封件的径向弹性管件(9)和一个固定于所述管件上或与其为一体的支撑件(13、13’、13”)，该支撑件有一个用于在管道内引导清管器的导向面(14)，该导向面的直径稍小于密封件的最大直径，使得当清管器通过管道的变形部分时该支撑件使管件径向变形。
