During normal operation, a collet sleeve is slidably engageable with a collet having one or more fingers that can releasably couple a first member with a second member.

Abstract: A breakaway coupling having a loop for receiving a connecting element. The loop includes a material reduction region. The material reduction region is formed as part of the loop such that the loop breaks at that region when placed under a pre-defined load. The coupling may be of fixed or swivel configuration. The material reduction region has dimensions less than the remainder of the loop such that-when the selected load is reached, the loop will break in that region. This design is particularly suited for those conditions when an underwater connecting element, such as a rope tied between an underwater lobster trap and a floating buoy, comes in contact with a marine animal. If the animal is of sufficient size, such as a whale, to apply the selected load to loop breakage, the connecting element will be released and the possibility of entanglement with the marine animal will be substantially reduced.

Abstract: A breakaway system for a compressed natural gas fueling hose. The system includes an upper ring that surrounds the fueling hose. A lower portion includes three concentric disks that are arranged as a gimbals. An outer disk is coupled to the upper ring with three rods. The lower portion surrounds a male connector.
