An electric clip, such as may be utilized with a leak detector, has a base which receives an insert to secure an inserted material, such as a mesh, there between. The insert has an arm with opposing hooks which pass through a first slot in a biased manner and then spring out once through to provide an assembled configuration. The clip can be secured to the material, such as by directing fingers through a second slot in a biased manner which then return once through to retain on a ledge.
