    • A connection sleeve for a suction hose is furnished with a protective covering for strain-relieved conductors. The protective covering is attached at an inner jacket face of the suction hose. A first sleeve part engages in part in the suction hose. A recess is furnished in the first sleeve part and a strain-relieving element, guided out of the protective covering, is fixedly positioned in said recess. A second sleeve part, gripping around and encircling the suction hose, covers the recess and the first sleeve part and the second sleeve part are connected to each other. The recess for the strain-relieving element (5) is an annular groove (6). An axial slot (7) extends from an insertion end of the first sleeve part (1). The axial slot (7) passes through a first collar (8), forming a first wall of the annular groove (6), and extends up to a second collar (9), forming a second wall of the annular groove (6). Flanks of the axial slot (7) pass over into a tubular formation (10), formed for receiving a coordinated end of the protective covering (4). The formation (10) is open toward the end of the axial slot (7) and closed at the opposite end. A section of the strain-relieving element (5), forming a loop, encircles a bottom of the annular groove (6), whereas free ends (5a) of the loop are guided through the axial slot (7) into the protective covering (4).
    • 用于抽吸软管的连接套管配有一个用于应变消除导体的保护盖。 保护罩安装在抽吸软管的内套面上。 第一套筒部分接合在抽吸软管中。 在第一套筒部分中设置有凹部,并且从保护罩引出的应变消除元件固定地定位在所述凹部中。 夹紧并包围抽吸软管的第二套筒部分覆盖凹部,第一套筒部分和第二套筒部分彼此连接。 用于应变消除元件(5)的凹部是环形槽(6)。 轴向槽(7)从第一套筒部分(1)的插入端延伸。 轴向槽(7)穿过第一套环(8),形成环形槽(6)的第一壁,并延伸到第二套环(9),形成环形槽(6)的第二壁。 轴向狭槽(7)的侧面通过成形为用于接收保护罩(4)的协调端的管状结构(10)。 地层(10)向轴向槽(7)的端部敞开,在相对端封闭。 形成环的应变消除元件(5)的一部分环绕环形槽(6)的底部,而环的自由端(5a)被引导通过轴向槽(7)进入保护罩( 4)。
