ABSTRACT:
A cap member has an annular wall extending from one side thereof. Interior threads are formed around the inside of said annular wall whereby the cap may be screwed to the exterior threads of a connector to close an opening. Two angularly spaced apart slots are formed through the annular wall of the cap member transverse to the axis thereof. The annular free edge of the wall next to each slot is deformed into each slot a small amount and a gap is formed through each of the deformed portions of the annular wall.
