The device is a snap buckle with a safety feature - an additional catch whic h prevents the buckle from being inadvertently disengaged. A male plug (10), having side catch arms (11a, 11b) and a central member (12) with a central member catch (17a) forms one part of the device. A female socket (13), havin g a hinged member (14) with a hinged member catch (18a) forms the other part o f the device. To engage, plug (10) and socket (13) are urged together until si de catch arms (11a, 11b) and central member catch (17a) on central member (12) both engage socket (13). To disengage, hinged member (14) is depressed to disengage central member catch (17a) on central member (12) while simultaneously side catches (11a, 11b) are depressed to disengage them from socket (13). |
