A sealing gland is provided for forming a seal between a plurality of elongate members and a surface having an aperture, or a pipe, through which the elongate members extend. The sealing gland includes a main sealing portion for sealing to the surface or the pipe. Skirts extend from a base of the sealing gland, where each skirt includes a lumen extending from the base to a distant end of the skirt for receiving one of the elongate members. Each skirt provides a flexible seal for sealing around a periphery of the elongate member, and adjacent skirts are adjoined along a portion of the length of the skirts.

1. A sealing gland for forming a seal between a plurality of elongate members and a surface having an aperture, or a pipe, through which said elongate members extend, said sealing gland comprising: a main sealing portion for sealing to the surface or the pipe,a plurality of skirts extending from a base of the sealing gland, each skirt comprising a lumen extending from the base to a distal end of the skirt for receiving a said elongate member, each skirt providing a flexible seal for sealing around a periphery of a said elongate member, andadjacent skirts in the plurality of skirts adjoined along a portion of the length of the skirts;the skirts comprising a stepped external surface and a stepped internal surface, internal steps of the stepped internal surface positioned closer to a distal end of the skirt than external steps of the external surface. 2. A sealing gland as claimed in claim 1, wherein the adjacent skirts are adjoined along approximately half the length of the skirts, from the base to approximately midway along the length of the skirts. 3. A sealing gland as claimed in claim 1, wherein at least one said skirt comprises a closed end, the skirt comprising the closed end adapted to be cut to provide an aperture for a said elongate member to extend through. 4. A sealing gland as claimed in claim 1, where each said skirt comprises a closed end. 5. A sealing gland as claimed in claim 1, wherein the internal surface of the skirt between each internal step provides a sealing surface for sealing about a said elongate member. 6. A sealing gland as claimed in claim 5, wherein each said sealing surface is tapered narrowing from a first diameter to a second diameter towards a distal end of the skirt. 7. A sealing gland as claimed in claim 1, wherein the wall of each skirt comprises at least one step formed in the portion of the length of the skirt adjoined with an adjacent skirt. 8. A sealing gland as claimed in claim 1, wherein each skirt comprises at least one step in the wall between the distal end of the skirt and the portion of the length of the skirt adjoined to an adjacent skirt. 9. A sealing gland as claimed in claim 1, wherein adjacent skirts in the plurality of skirts are adjoined along a portion of the length of the skirts extending from the base to a step in the external surface of the wall of the skirt. 10. A sealing gland as claimed in claim 1, wherein an internal diameter of a said skirt at an extent of a join between the walls of two adjacent adjoined said skirts is a maximum aperture size of that skirt. 11. A sealing gland as claimed in claim 10, wherein an internal surface of the skirt extending from the maximum aperture towards the base is a sealing surface for sealing about a said elongate member. 12. A sealing gland as claimed in claim 1, wherein each skirt is adjoined to two adjacent skirts. 13. A sealing gland as claimed in claim 1, wherein the base comprises a thickness greater than a thickness of the wall of the skirt. 14. A sealing gland as claimed in claim 13, wherein the thickness of a portion of the base that is encircled by the skirts is greater than the thickness of a portion of the base outside the plurality of skirts. 15. A sealing gland as claimed in claim 14, wherein the thickness of a portion of the base that is encircled by the skirts is at least twice the thickness of a portion of the base outside the plurality of skirts. 16. A sealing gland as claimed in claim 1, wherein the sealing gland comprises four skirts. 17. A sealing gland as claimed in claim 1, wherein the main sealing portion of the sealing gland comprises a flange for sealing to the surface, the flange projecting radially outwards from an open end of the sealing gland. 18. A sealing gland as claimed in claim 17, wherein the sealing gland comprises a retaining lip for retaining a compression ring in place against the flange. 19. A sealing gland as claimed in claim 18, wherein the flange is coplanar with the base. 20. A sealing gland as claimed in claim 18, wherein the flange is provided at an open end of the sealing gland spaced from the base in a longitudinal direction, the sealing gland comprising an internal cavity between the base and the flange. 21. A sealing gland as claimed in claim 1, wherein the main sealing portion of the gland comprises a tubular section extending from the base for sealing to an end of a pipe from which the elongate members extend. 22. A sealing gland as claimed in claim 1, wherein the main sealing portion of the sealing gland comprises an annular groove formed between a retaining lip and an annular shoulder, the annular groove for receiving a perimeter of the aperture in the surface of a wall, in use the groove retaining the wall between the retaining lip and the shoulder to form a seal with the surface. 23. A sealing gland as claimed in claim 1, wherein the sealing gland comprises an internal cavity between the base and an open end of the sealing gland, the lumen of each skirt extending from a distal end of each skirt and the internal cavity. 24. A sealing gland as claimed in claim 1, wherein the lumen of each skirt extends the full length of the sealing gland from the distal end of the skirt to an open end of the sealing gland. 25. A sealing gland as claimed in claim 1, wherein the sealing gland is a unitary member.
