ABSTRACT: There is disclosed a strip structure (10) intended for clamping engagement on a flange or like member, the strip structure (10) having a channel defined by a base (12) and two opposed side walls (13,14), each side wall being provided with an elongate limb (16,17) directed inwardly and towards the base (12) such that the limbs (16,17) abut at their free end regions (20,21); wherein that face of each limb (16,17) which faces the corresponding face of the other limb (16,17) is straight or substantially straight over a portion of the limb in the region of the free end (20,21); wherein the side walls (13,14) are also each provided with an inward projection (26,27) nearer the base (12) of the channel than the root of the limb (16,17); and wherein each of the limbs (16,17) is provided on that face which faces the side wall (13,14) with a recess (22,23) in which the projection may be accommodated; the arrangement being such that, in use, when the strip structure (10) is being clamped on a flange or like member, the flange causes the limbs (16,17) to be moved apart, with the projections (26,27) being accommodated in the corresponding recess (22,23), whereby the clamping may be effected without undue force, but, when an attempt is made to remove the strip structure (10) from the flange, the free end regions (20,21) of the limbs (16,17) grip the flange and the limbs (16,17) are restrained from undue movement towards the open end of the channel by the interaction of the projections (26,27) and the limbs (16,17) in the region of the recesses (22,23) of the latter, the configuration of the limbs (16,17) and the effect of said interaction being such that considerably more force is required to remove the strip structure (10) from the flange than is required to clamp the strip structure (10) on the flange. Preferably, each limb (16,17) has a length, as measured along the face which faces the corresponding face of the other limb (17,16), which exceeds the width of the channel at the point where the root of the limb (16,17) projects from its respective side wall (13,14). It is also preferred for the limbs (16,17) to be formed, on at least those surface regions which face the opposing limb, from a polished plasticised polyvinyl chloride material.
