A fixture of the safety device used in conjunction with a medical needle, medical needle protrudes from the transporting part of the substantially cylindrical transport section includes at least two ribs of space around The cage, ribs extending substantially parallel and upright with respect to the axis of the transport section. When the wall lying in a substantially radial direction with respect to conveying portion is used, the fixture includes a cylindrical support portion including a wall having an opening of the central conveying portion extends. Surrounds the transportation section, hole, to a recess to accept the ribs of the transport section. And to confirm the holes and recesses for engagement with the ribs of the transport section, the projections of the wall, connected to mutual between the portion of the wall which is adjacent to the rib of the transport section. [Selection Figure Figure 5医療用針に関連して使用される安全装置についての取り付け具であって、医療用針は略円筒状の運搬部から突出しており、運搬部は周囲に空間のあるリブを少なくとも2つ含んでおり、リブは運搬部の軸に対して直立かつ略平行に伸びる。取り付け具は、運搬部に対して略半径方向に横たわる壁面が使用されるときに、運搬部が延伸する中央の開口部を有する壁を含む円筒状支持部を有している。孔は、運搬部を囲み、運搬部のリブを受け入れる凹部をする。壁の突起は、運搬部のリブと係合する穴と凹部とを確定し、運搬部のリブと隣接する壁の部分との間を相互的に接続する。【選択図】図5
