    • The invention relates to an attachment for a syringe, carpule (81) or the like that has a distal end (91) and a terminating protrusion (79) thereon, wherein the protrusion (79) has an outer surface (83), a free end (85) and at least one recess (87) introduced into the outer surface at a distance therefrom. The attachment (1) has an annular main body (15) and can be placed on the protrusion (79). The main body (5) encloses a free space (7) into which the protrusion (79) can be introduced. The main body (5) comprises two materials, preferably consisting thereof, of which a first material is dimensionally stable and a second material is softer than the dimensionally stable first material and deformable. The main body (5) has at least one engagement region which engages with the at least one recess (87) when positioned on the protrusion (79). The attachment is characterized in that, along an imaginary circumferential line, the main body (5) has at least one first region with the first material and at least one second region with the second material, wherein the second material is deformed into the at least one recess (87) when attached to the protrusion (79), and wherein the second material is embedded into the first material.
    • 用于注射器,小胡子等的附件包括具有外表面,自由端和以一定间隔引入外表面的凹陷的末端和终端延伸部。 附件包括环形基体并且可放置在延伸部上。 基体包围一个可伸缩的空间。 基体包含两种材料,第一材料尺寸稳定,第二材料比第一材料柔软并可变形。 基体具有接合到凹陷中的接合区域。 延伸部的特征在于,基体沿着假想的圆周线具有第一区域和第二区域,第二区域包含第二材料。 第二种材料在放置到拉伸状态下变形成凹陷。 第二种材料被嵌入到第一种材料中。
