Breakaway retention device (100) is comprises a retained member (120) and a retention body (110). The retention member includes a retention knob (121). The retention body includes a housing having one or more resilient components (113a and 113b), two or more retention members (114a, 114b, 114a, and 114d), and a retention space (118). The retention space is at least partially defined by the retention members and configured to receive the retention knob when the retained member and the retention body are coupled together. The resilient components are disposed to resiliently maintain each of the retention members 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. The retained member and the retention body are prevented from being decoupled without the application of a predetermined force.
