The present invention relates to a staple for holding a tubular member within a corrugated conduit, wherein the tubular member comprises an outer surface, and the corrugated conduit comprises an open end and an inner surface with successive and alternating annular peaks and valleys. The stapl e comprises a mechanically compliant convex wall slanted in a direction opposi te to a direction of insertion of the tubular member in the corrugated conduit through the open end of this corrugated conduit. The latter mechanically compliant convex wall includes: an elongated wall base connected to the oute r surface of the tubular member; a sloping convex surface for sliding over the annular peaks and valleys upon inserting the tubular member in the corrugate d conduit through the open end of this corrugated conduit; and a free edge for engaging the inner surface of the corrugated conduit and thereby locking the tubular member inside the corrugated conduit when the mechanically compliant convex wall has been inserted in one of the valleys of the inner surface of the corrugated conduit. The present invention is further concerned with an insid e cap for closing an open end of a corrugated conduit, and with a coupling for interconnecting first and second corrugated conduits both incorporating the above described staple.
