Abstract

A cap for installation over the open end of a tubular member that has a pipe or pipes of smaller diameter projecting through the open end of the tubular member. The cap has a rubber discoid portion that covers the open end of the tubular member and a rubber apron extending from the discoid portion and adapted to encircle the tubular member adjacent to its open end. An aperture or apertures for the pipes of smaller diameter are provided in the discoid portion. The cap is split except at the back where a portion including the apron provides a hinge. The split intersects the aperture or apertures. A split, flexible metal band is embedded in the apron and has a latch for tightening and locking the apron about the tubular member. To install the cap, it is hinged open and placed over the end of the tubular member with the smaller diameter pipes passing through the apertures, and is then closed around the tubular member and locked.
