    • A fastener that can be used in various applications, that is more durable than known fasteners, and that increases the removal forces necessary to remove the fastener from the connecting substrate is made of a plastic material that defines a base and one or more fastening legs. The fastening legs extend outwardly from the base, are joined together at a common post and connect to the base at leg ends. Each of the fastening legs may have an angled surface at the leg ends and near the base. This angled surface provides a contact surface with the substrate to which the fastener is mounted and also increases the removal force needed to remove the fastener from the substrate. The leg ends are connected to the base and define a thickness at this connection point that provides sufficient flexibility for installation to the connecting substrate to prevent damage to the fastening legs so that greater extraction forces will be necessary to remove the fastener from the connecting substrate.
    • 可以在各种应用中使用的紧固件,其比已知的紧固件更耐用,并且增加从连接基板移除紧固件所必需的去除力由限定基部和一个或多个紧固腿的塑料材料制成。 紧固腿从基座向外延伸,以共同的柱连接在一起,并在腿端连接到基部。 每个紧固腿可以在腿部端部和基部附近具有成角度的表面。 该成角度的表面提供与紧固件所安装的基底的接触表面,并且还增加了从衬底移除紧固件所需的去除力。 腿端连接到基座并且在该连接点处限定厚度,其提供足够的柔性以安装到连接基底以防止损坏紧固腿,使得需要更大的提取力来从连接基底移除紧固件。
