Dispositif de boucle
The present invention relates to a buckle device used in child seats of a baby carriage or high chair, comprising first and second waist-strap adjusting device, first and second plug for waist-strap, first and second shoulder strap-coupling device, a socket and a release button. Each of the first and second plugs for waist-strap includes a arm that can be inserted into the socket. Each of the plugs has, in between the arms, a resilient tongue that can be inserted into the socket. The socket has a hole for receiving the release button, and has resilient legs at the bottom thereof so that the release button may maintain in position. The release button includes cavities at both sides thereof for receiving the arms. The release button further includes inclined surfaces corresponding to the resilient tongue between the cavities. When the release button is pressed, the inclined surfaces will exert a force on the resilient tongue to eject the plug from the socket.
