CA 2533566

A leak containment device for a well-head includes a resilient hollow inverted frusto-conical upper section having a narrow end at a lower end of the upper section and an annular collar mounted to the lower end of the upper section so as to extend downwardly therefrom. The upper section and the collar co-axial are about a substantially vertical axis of symmetry when mounted on the well-head. A spigot is mounted in fluid communication with, so as to extend from a side of the lower end. A contiguous separatable seam is formed in the upper section and the collar so as to allow resilient deformation of the upper section and the collar to open the seam into an open position for passage of the well-head into the upper section and the collar. The collar is sized for snug mating engagement around the well-head when the seam is resiliently returned to, and releasably locked in a closed position wherein the seam is closed fluid-tight so as to inhibit fluid leakage through the seam.
