Presented is a coupling device designed to release two members that are connected together when more than a predetermined force is exerted to separate the two members. The coupling device is adjustable to increase or decrease the amount of force to which it responds. Structurally, the device includes a plug member having a spherical knob seated in a complementary seat formed in a surrounding tube having longitudinal slits. A sleeve surrounding the tube is slidable between maximum and minimum force settings to control the amount of force required to separate a member connected to the plug member from another member connected to the tube.
