    • An improved assembly, composed of a hard member and a soft tube fitted onto the hard member, for medical uses is formed with a plurality of projections on the side wall of a flange of the hard member. The projections project toward the soft tube side to firmly hold the foremost end part of the soft tube between the projections and a fitting portion of the hard member in a clamped state when the soft tube is fitted onto a fitting portion of the hard member. The foremost end surface of the soft tube may slantwise be cut to define a certain angle relative to the center axis of the assembly such that the foremost end part of the soft tube comes in tight contact with the side wall of the flange when the soft tube is fitted onto the fitting portion of the hard member. The soft tube may be formed with a plurality of cutouts which are arranged along the periphery of the foremost end surface of the soft tube in a spaced relationship. Each cutout preferably exhibits a V-shaped contour which defines a certain opening angle symmetrically relative to the center axis of the assembly.
    • 在硬质构件的凸缘的侧壁上形成有用于医疗用途的安装在硬质构件上的硬质构件和软管构成的改进组件。 当软管装配到硬质构件的装配部分上时,突出部朝向软管侧突出地将柔性管的最前端部牢固地保持在突出部与硬质构件的装配部之间。 软管的最前端表面可以倾斜地切割以相对于组件的中心轴线限定一定角度,使得软管的最前端与凸缘的侧壁紧密接触,当软管 安装在硬质构件的嵌合部上。 软管可以形成有多个切口,它们以间隔的关系沿着软管的最前端表面的周边布置。 每个切口优选地呈现出相对于组件的中心轴线对称地限定一定开口角度的V形轮廓。
