Abstract: A coupling device for connecting a filter element to a filter conduit has male and female couplings each having a passageway for fluid. The male coupling is secured to the filter conduit and has at least two radially projecting lugs. The female coupling is secured to the filter element and has at least two latching tabs for engaging the lugs. A spring is operatively mounted on the male coupling and interferes with the radially projecting lugs. The spring is disposed so as to engage at least one latching tab when the male and female couplings are moved toward each other. The spring urges the latching tabs to rotate in a first angular direction thereby causing the tab to latch to a lug of the male coupling.

Abstract translation: 用于将过滤元件连接到过滤器管道的联接装置具有每个具有用于流体的通道的阳联接器和阴联接器。 阳联接器固定到过滤器导管并且具有至少两个径向突出的凸耳。 阴联接器固定到过滤元件上，并且具有用于接合凸耳的至少两个闩锁突出部。 弹簧可操作地安装在阳联接器上并且干扰径向突出的凸耳。 弹簧设置成当阳联接件和阴联接件彼此移动时与至少一个闩锁接头接合。 弹簧促使闩锁突片在第一角度方向上旋转，从而使突出部闩锁到阳联接器的凸耳上。
