Connection sleeve for a suction tube furnished with a wire protecting sheathing for strain relieved electrical conductors

A connection sleeve for a suction tube furnished with a wire protecting sheathing for strain relieved electrical conductors comprising:

• a suction tube having an inner jacket face;
• a wire protecting sheathing attached at the inner jacket face of the suction tube;
• a sleeve shaped sleeve body having a plug in end and having a front end, wherein an axial slot having flanks begins at the plug in end of the sleeve body, wherein the sleeve body is partially inserted and plugged into the suction tube;
• a pipe like body attached to the sleeve body and having a front end, wherein the flanks of the axial slot transition into the pipe like body, wherein the pipe like body is formed for receiving of a coordinated end of a wire protecting sheathing, wherein the pipe like body is open at the plug in end side of the sleeve body and wherein the pipe like body is closed at the front end of the sleeve body, and wherein the pipe like body is formed for receiving of a coordinated end of a wire protecting sheathing;
• an electrical conductor led out of the sleeve body in the region of a section of the axial slot not covered by the suction tube;
• a strain relieve element disposed in the pipe like body, wherein an end of the strain relieve element, protruding together with the electrical conductor out of the wire protective sheathing, is united pull safe with the sleeve body;
• a strain relieve element disposed in the wire protecting sheathing;
• a cross wall disposed at the front end of the pipe like body, wherein the strain relieve element grips through the cross wall disposed in the pipe like body and is aligned perpendicular to the axis of the sleeve body, and wherein the strain relieve element is secured in its position against pulling out with a thickening disposed on the side of the cross wall directed toward the front end of the sleeve body.
