The device is a snap buckle with a safety feature-an additional catch which prevents the buckle from being inadvertently disengaged. A male plug, having side catch arms and a central member with an additional catch, forms one part of the device. A female socket having a depressible member forms the other part of the device. To engage, plug and socket are urged together until the side catch arms, and the additional catch on the central member, both engage the socket. To disengage, the depressible member is depressed to disengage the additional catch on the central member, while simultaneously the side catch arms are depressed to disengage them from the socket. |
