Abstract
Plug and socket members of a break-away animal collar coupler are affixed to opposite end portions of a collar, each by a screw vising and optionally penetrating a collar end portion disposed in a cavity defined by an angular base member. In several embodiments the socket member comprises a second plug and a socket housing defining at opposite ends two sockets adapted to engage the plugs. The plugs are rigid and the socket housing is rubberized so as to disengage with a plug when a component of a force applied to the collar is of sufficient magnitude and in a direction urging disengagement. In an alternative embodiment, there is only one plug member and prongs of the plug member are rubberized whereas the socket has within it rigid shoulders which catch the prongs.
