−本体の2つの面上の界面に存在する接着剤の表面積を増やすことによって得られる接着界面
をさらに改善することが可能になることが認められるであろう。
−二重ヨークの形の接続端部が2つの平行な接続壁を含み、接続壁は、本体の中央の長手方向の平面の両側に末端部と共に単一部品として形成することができ、且つ接続ピンがこれらの構造体の1つまで横断するように設計された対向するオリフィスをそれぞれ備える(或いは、単一の接続壁を有する単一のヨークを使用することもできる)、固定されたタイプのもの、又は
−接続端部が、末端部に調節可能に挿入された管状の支持体を含み、且つ本体の長手方向の中央の平面の両側で2つの平行な接続壁を有する二重ヨークで終わり、こうした壁が、接続ピンがこれらの構造体の1つまで横断するように設計された対向するオリフィスをそれぞれ備える(或いは、単一のヨークを使用することもできる)、調節可能なタイプのもの
である。
a)前記末端部のそれぞれと接触する前記少なくとも1つの第1の封止ガスケット、及び前記本体に対向する端部領域の第1の半径方向内側又は外側の面を組み立てるステップ、次いで、
