ABSTRACT:
A cap for blocking a pipe. The pipe has a rim at an end thereof. The rim defines a pipe aperture. The cap includes a body for blocking the pipe aperture, the body including a bore having a threaded bore portion. A latch is movably mounted on the body for movement between a latched position wherein the latch engages the rim, and an unlatched position wherein the latch disengages the rim. A plug is provided for threaded engagement with the threaded portion and converts a rotational movement of the plug relative to the bore into a translation movement of the plug relative to the bore between a plug first position and a plug second position. The plug is operatively coupled to the latch for moving the latch between the latched and the unlatched positions in response to the plug being moved between the first plug position and a second plug position.
