Submarine cable protecting device

Abstract

A submarine cable protecting device in which a plurality of pairs of half members are connected in series, includes a cylindrical portion which encloses a submarine cable. An outside spherical surface extending from one end of the cylindrical portion is provided at one end of each of the half members. An inside spherical surface extending from the other end of the cylindrical portion is provided at the other end of each of the half members, the inside spherical surface being shaped such that the inside spherical surface of one of the half members encompasses the outside spherical surface of another of the half members and the outside spherical surface cannot be detached from the inside spherical surface when the two half members are connected in series. The outside spherical surfaces of one pair of the half members has a reduced outside diameter when the outside spherical surfaces are contacted and the inside spherical surfaces are separated. The outside spherical surfaces are inserted into the inside spherical surfaces of another pair of the half members, and the two pairs of the half members are connected in series when the inside spherical surfaces are contacted.
