Abstract

A housing device for a pipeline having valves extending from a horizontal segment, the device comprising:
- (A) a generally rectangular base member having a bottom, two side walls, two end walls and an upper mating surface connected together to define an open interior to receive the valves of a pipeline, where each of the two end walls further comprise a semi-circular pipe receiving channel;
- (B) mounting means to connect said base member to the horizontal segment of said pipeline;
- and
- (C) a generally rectangular cover member having a top, two side walls, two end walls and a lower mating surface connected together to define an open interior to receive the valves of said pipeline, where each of the two end walls further comprises a semi-circular pipe receiving channel;
- where said cover member and said base member in combination enclose said valves with said upper mating surface and said lower mating surface abutting each other, and where said cover member is removable from said base member while said base member remains connected to said horizontal segment of said pipeline.
