Abstract
A closure indicator for a fluid coupling is disclosed where the fluid coupling has first and second semi-circular members hinged together at a first end and latched together at the opposite end, the indicator comprising an upper surface including a stop on a rear surface for arresting rotational travel in a first direction, first and second sidewalls with elongate slots, a spring biasing the indicator in the first direction, and first and second arms extending from said first and second sidewalls, respectively, to a position under a pin of a bracket only when the members are latched together.

A closure indicator for a fluid coupling, the fluid coupling having first and second semi-circular members hinged together at a first end and at the other end having opposed brackets each with a respective parallel pin with latches for closing the fluid coupling, the indicator comprising:
- an upper surface including a stop on a rear surface for arresting rotational travel in a first direction;
- first and second sidewalls, each sidewall including an elongate slot through which a first pin of a bracket is received, the elongate slots having a height substantially equal to a diameter of the first pin and a length greater than the height for rotational and translational movement of the indicator about the first pin;
- a spring biasing the indicator in the first direction;
- and
- first and second arms extending from said first and second sidewalls, respectively, to a position under a second pin of a bracket only when the latches are in a closed position and only when the indicator is moved along the first pin to a forward most position with respect to said elongate slot.
