A tubular insertion aid for catheter manipulation is disclosed. The insertion aid is particularly suited for urinary catheters, such as hydrophilic urinary catheters for intermittent use. The insertion aid comprises a forward opening, a rearward opening and a slit opening extending along a part of the sidewall of the tubular insertion aid, so that a first portion of the tubular insertion aid in the axial direction forms a solid circumference around the tubular insertion aid, and a second portion in the axial direction is provided with the slit opening extending in an axial direction of the tubular insertion aid. The tubular insertion aid further comprises a first inward protrusion formed on the interior side of the tubular insertion aid in a part of the second portion being provided with the slit, wherein the first inward protrusion is arranged along a first protrusion line extending along the inward circumference of the tubular insertion aid essentially perpendicularly to the axial direction of the tubular insertion aid.

1. A tubular insertion aid for catheter manipulation, comprising a forward opening, a rearward opening and a slit opening extending along a part of the sidewall of the tubular insertion aid, so that a first portion of the tubular insertion aid in the axial direction forms a solid circumference around the tubular insertion aid, and a second portion in the axial direction is provided with the slit opening extending in an axial direction of the tubular insertion aid, the tubular insertion aid further comprising a first inward protrusion formed on the interior side of the tubular insertion aid in a part of the second portion being provided with said slit, wherein the first inward protrusion is arranged along a first protrusion line extending along the inward circumference of the tubular insertion aid essentially perpendicularly to the axial direction of the tubular insertion aid, such that said slit opening provides an increased flexibility to the tubular insertion aid. 2. The tubular insertion aid of claim 1, further comprising a second inward protrusion formed on the interior side of the tubular insertion, the second inward protrusion being arranged along a second protrusion line extending along the inward circumference of the tubular insertion aid essentially perpendicularly to the axial direction of the tubular insertion aid, wherein the second protrusion line is separated from the first protrusion line in the axial direction of the tubular insertion aid. 3. The tubular insertion aid of claim 2, wherein the second protrusion line is arranged at or adjacent to the junction between the first and second portions of the tubular insertion aid. 4. The tubular insertion aid of claim 2, wherein said second inward protrusion is formed directly forward of said slit opening such that it functions as a stop to prevent further advancement of the tubular insertion aid. 5. The tubular insertion aid of claim 1, wherein the second portion of the tubular insertion aid extends between the first portion of the tubular insertion aid and the rearward opening of the tubular insertion aid, and wherein the slit opening of the second portion does not extend all the way up to the rearward opening, thereby forming a solid circumference around the tubular insertion aid in the vicinity of the rearward opening such that said increased flexibility is only provided at an intermediate part of said tubular insertion aid. 6. The tubular insertion aid of claim 5, wherein the solid circumference around the tubular insertion aid in the vicinity of the rearward opening is provided with a reduced wall thickness in the extension of the slit opening than in the rest of the circumference. 7. The tubular insertion aid of claim 1, wherein the tubular insertion aid is at least partly funnel shaped. 8. The tubular insertion aid of claim 1, wherein the rearward opening has a greater cross-sectional dimension than the forward opening. 9. The tubular insertion aid of claim 1, wherein the first portion is provided with gripping means on the outwardly facing side. 10. The tubular insertion aid of claim 9, wherein the gripping means is formed by at least one of outward protrusions, corrugations, embossment and perforations. 11. The tubular insertion aid of claim 1, wherein the tubular insertion aid is made of a flexible plastics material, such as any combinations of a thermoplastic material, a thermosetting plastic material or a thermoplastic elastomer material. 12. A catheter set comprising a catheter and the tubular insertion aid of claim 1, wherein the catheter comprises a forward insertion part and a rearward connector part, wherein the connector part forms a waist having a cross-sectional dimension of lower extension than the surrounding portions of the connector part, and wherein, in a storage position, the insertion aid is arranged around the connector part of the catheter so that the first protrusion line of the tubular insertion aid overlies said waist of the catheter, thereby detachably connecting the tubular insertion aid to the catheter. 13. The catheter set of claim 12, wherein the connector part of the catheter and the tubular insertion aid are both made of the same material. 14. The catheter set of claim 12, wherein the catheter is a hydrophilic catheter, wherein the forward insertion part is at least partly provided with a hydrophilic material exhibiting low-friction surface properties when wetted. 15. The catheter set of claim 12, wherein the catheter is a urinary catheter, and preferably a urinary catheter for intermittent use. 16. A catheter assembly comprising a catheter set of claim 12 and a package enclosing said catheter set. 17. The tubular insertion aid of claim 1, wherein said first protrusion line and said slit intersect each other. 18. The tubular insertion aid of claim 1, wherein said slit extends partly in said axial direction of said tubular insertion aid, and partly in other directions in relation to said axial direction.
