Le corps principal de faisceau 10 est constitué de multiples fils électriques 11 dont chacun comporte une âme 12 et une couche de revêtement isolant 13 recouvrant l'âme 12. Les multiples fils électriques 11 sont groupés pour former un faisceau de fils électriques 11B, et une partie terminale 11E de chaque fil électrique 11 se ramifie respectivement à partir du faisceau de fils électriques 11B. Le corps extérieur 20 est monté sur l'extérieur du faisceau de fils électriques 11B. Le corps extérieur 20 comporte une fente 21 s'étendant le long de la direction axiale du corps extérieur, et est équipé d'une paire de parties lèvres 22, 22 disposées en regard l'une de l'autre, cette fente 21 étant prise en sandwich entre elles. La partie du corps extérieur autre que la paire de parties lèvres 22, 22 forme un corps principal de tube 23. Les parties lèvres 22, 22 sont formées à partir d'un matériau plus mou que le corps principal de tube 23.
