A retaining plate (30) made from a rigid material having tips on each of the two faces of same, the tips of each of the faces of a length of between 1 and 3 mm making an angle in the forward direction with the face of between 30 and 60. The retaining plate is secured by the tips of one of the faces of same at the final end (28) of a first reinforcing strip (26) already positioned on the degraded portion of a pipe, and secured to the initial end (32) of a second reinforcing strip to be wound following the first reinforcing strip by the tips of the other face, said tips being tilted towards the initial end (32) of the second reinforcing strip.

An apparatus for providing an interstitial space to the surface of wall, the apparatus comprises: an adhesive layer; a layer of fluid impervious and weather proof material in form of a tape, the tape partially overlapping itself; a layer of spacer material situated between the surface of the tape facing the wall and the surface of the adhesive layer distal from the wall. The spacer material has ends which are encapsulated, the apparatus providing a sealed interstitial space.

The present invention relates to an anti-corrosion tape, in particular for producing a pipe covering, comprising at least one bonding ply, produced from a material selected from the group including at least one butyl rubber and/or at least one polyisobutylene, at least one bidirectional woven fabric being at least partially embedded in the at least one bonding ply.
