A breakaway retention device, comprising: a retained member, comprising a retention knob; and a retention body comprising a housing, wherein the housing comprises: one or more resilient components (113a, 113b), two or more retention members (114a ― 114d), and a retention space at least partially defined by the retention members (114a ― 114d) and configured to receive the retention knob when the retained member and the retention body are coupled together, wherein the resilient components (113a, 113b) are disposed to resiliently maintain each of the retention members (114a ― 114d) in a predetermined engagement position in the retention body to engage the retention knob when the retained member and the retention body are coupled together, whereby the retained member and the retention body are prevented from being decoupled without the application of a predetermined force characterized in that the retention body further comprises a fulcrum disposed adjacent to one of the one or more resilient components (113a, 113b) and on a side of the resilient component (113a, 113b) that does not include a retention member, and wherein: the fulcrum comprising a moving assembly configured to slidably move the fulcrum, and impacting a flexing point of a corresponding resilient component (113a, 113b) to control movement of a retention member corresponding to the resilient component (113a, 113b); and thereby adjusting a breakaway force required to decouple the retention body from the retained member when the retention body and the retained member are coupled together. a retained member, comprising a retention knob; and a retention body comprising a housing, wherein the housing comprises: one or more resilient components (113a, 113b), two or more retention members (114a ― 114d), and a retention space at least partially defined by the retention members (114a ― 114d) and configured to receive the retention knob when the retained member and the retention body are coupled together, wherein the resilient components (113a, 113b) are disposed to resiliently maintain each of the retention members (114a ― 114d) in a predetermined engagement position in the retention body to engage the retention knob when the retained member and the retention body are coupled together, whereby the retained member and the retention body are prevented from being decoupled without the application of a predetermined force characterized in that the retention body further comprises a fulcrum disposed adjacent to one of the one or more resilient components (113a, 113b) and on a side of the resilient component (113a, 113b) that does not include a retention member, and wherein: the fulcrum comprising a moving assembly configured to slidably move the fulcrum, and impacting a flexing point of a corresponding resilient component (113a, 113b) to control movement of a retention member corresponding to the resilient component (113a, 113b); and thereby adjusting a breakaway force required to decouple the retention body from the retained member when the retention body and the retained member are coupled together. one or more resilient components (113a, 113b), two or more retention members (114a ― 114d), and a retention space at least partially defined by the retention members (114a ― 114d) and configured to receive the retention knob when the retained member and the retention body are coupled together, wherein the resilient components (113a, 113b) are disposed to resiliently maintain each of the retention members (114a ― 114d) in a predetermined engagement position in the retention body to engage the retention knob when the retained member and the retention body are coupled together, whereby the retained member and the retention body are prevented from being decoupled without the application of a predetermined force characterized in that the retention body further comprises a fulcrum disposed adjacent to one of the one or more resilient components (113a, 113b) and on a side of the resilient component (113a, 113b) that does not include a retention member, and wherein: the fulcrum comprising a moving assembly configured to slidably move the fulcrum, and impacting a flexing point of a corresponding resilient component (113a, 113b) to control movement of a retention member corresponding to the resilient component (113a, 113b); and thereby adjusting a breakaway force required to decouple the retention body from the retained member when the retention body and the retained member are coupled together. the fulcrum comprising a moving assembly configured to slidably move the fulcrum, and impacting a flexing point of a corresponding resilient component (113a, 113b) to control movement of a retention member corresponding to the resilient component (113a, 113b); and thereby adjusting a breakaway force required to decouple the retention body from the retained member when the retention body and the retained member are coupled together.
