1. A coupling for fitting to an externally corrugated elongate member, the coupling comprising:

  • a body having one end adapted to receive the elongate member and an opposite end provided with coupling means by which the coupling can be connected with a cooperating coupling; and

    annular retaining means carried by the body, at least part of said annular retaining means being rotatable in a plane transverse to an axis of the elongate member and fixed relative to the body, the retaining means and the body having cooperating cam surfaces, the retaining means having at least one internally-projecting surface formation and at least one manually-engageable member that projects from the body such that by engaging the manually-engageable member and rotating it in said plane, the cam surfaces rotate relative to one another and thereby displace the surface formation between a first position in which the surface formation is located relatively outwardly to enable entry of the corrugated member into the body and within the retaining means, and a second position in which the surface formation is located relatively inwardly to lie between adjacent corrugations on the elongate member and lock it in the body, and wherein the retaining means cannot be removed from the body while the elongate member is inserted within the body.
