Device for joining plates or manufacturing pipes.

摘要

Device composed of two parts (I) and (J) which fit together by the deformation of longitudinal projections (3) into the corresponding recesses (4), these parts being obtained from a single shaped strip of a flexible polymeric composition, characterised in that a slot (31) is formed in the axis of the projections (3) where a line of staples (32) renders said projections (3) nondeformable. <IMAGE>
