This invention consists of a device on protective pipes designed to be exposed in buildings and used as protection for primarily soft lines wired for water, heat and similar, in said pipes where the joints between the protective parts are arranged there are penetration openings for lines which are bifurcated from the lines L in the protective pipe. The new invention consists of said penetrations being formed by interacting telescopically-arranged parts 3, 6, where one has at least one essentially straight axially-arranged slit 8 which reaches from the parts' end edge, while the other part has at least one L-, alternatively F-shaped slit 7, 7a, with the stacking part axially, and the protrusions peripherally, oriented in order to allow the axial collapse of the parts around one, alternatively two, in the lines axial direction, in the lines after each other, radially protruding line pipes and locking, by one part being turned in relation to the other while the line pipe or line pipes run in to the L-, or respectively F-shaped slits 7 cross- sectional slit part or slit parts 7' respectively. <IMAGE> |
