Strip structure intended for clamping on a flange

摘要

A strip structure intended for clamping on a flange has a channel defined by a base and two opposed side walls. At least one limb with a free depending end directed toward the base is positioned and secured on one of the side walls. An inward projection is also positioned on the side wall to which the limb is secured and adjacent to the limb. The limb has one face facing one side wall and another face facing the other side wall. The face facing the side wall to which the limb is secured has a recess therein which accommodates the projection on the side wall so that the strip structure can be attached onto a flange without undue force but strongly resists removal from the flange.
