A hose coupling includes a hose coupling member and a cover. The cover includes a cover face and a connecting portion. The cover and the hose coupling member are locked through a locking structure. The locking structure includes a handle, an opening, and an annular limit groove. The annular limit groove is disposed around a circumferential wall of the connecting portion. The opening penetrates a side wall of the hose coupling member. One end of the handle is a curved limit portion to mate with the annular limit groove. The limit portion penetrates the opening to be engaged in the limit groove and is hinged on the hose coupling member through a pivot seat. The pivot seat includes a first seat and a second seat. Outer ends of the first seat and the second seat are each formed with a pin hole for a safety pin to be inserted therethrough.

A waterway installation structure in a toilet includes a connection module. The connection module includes a module body including a watercourse and includes at least two connection pipe joints disposed on the module body and in fluid communication with the watercourse. The waterway installation structure in the toilet also includes at least two waterway modules. The at least two waterway modules include at least two waterway joints configured to be respectively connected to the at least two connection pipe joints. The at least two waterway joints are configured to be respectively inserted into the at least two connection pipe joints, or the at least two connection pipe joints are configured to be respectively inserted into the at least two waterway joints.

A lockout tagout device associated with a fitting includes a body having a first body portion and a second body portion. The second body portion is movable relative to the first body portion about an axis of rotation to transform the body between a closed configuration and an open configuration. The lockout tagout device is connectable to the fitting such that the axis of rotation is oriented parallel to a longitudinal axis of the fitting.
