A connector for a flexible pipe comprises a connector body having an end portion for coupling to a flexible pipe. The end portion includes a frusto-conical portion and an adjacent cylindrical portion. The frusto-conical portion has its widest portion adjacent the cylindrical portion and has a diameter greater than the diameter of the cylindrical portion and forms a radially extending substantially transverse shoulder with the cylindrical portion to force the pipe to form a bulge around the shoulder. The frusto-conical portion has its narrowest portion with a diameter slightly less than the inside diameter of the pipe to facilitate insertion into the pipe. A ring has a cylindrical inner surface with an inside diameter substantially equal to the outside diameter of the pipe. The ring is positioned to overlie the shoulder thereby to compress the bulge against the shoulder and seal the pipe to the connector body.

We claim: 1. A flexible pipe and connector assembly, comprising: a) a connector body for coupling to the flexible pipe; b) said connector body including a frusto-conical portion and an adjacent cylindrical portion, said frusto-conical portion tapering from wide to narrow into the pipe; c) said frus
We claim: 1. A flexible pipe and connector assembly, comprising: a) a connector body for coupling to the flexible pipe; b) said connector body including a frusto-conical portion and an adjacent cylindrical portion, said frusto-conical portion tapering from wide to narrow into the pipe; c) said frusto-conical portion having its widest portion adjacent said cylindrical portion and having a diameter greater than the diameter of said cylindrical portion and forming a radially extending substantially transverse shoulder with said cylindrical portion to force the pipe to form a bulge around said shoulder; d) said frusto-conical portion having its narrowest portion with a diameter slightly less than the inside diameter of the pipe thereby facilitating insertion of said frusto-conical portion into the pipe and e) a solid ring without radial holes, said ring having a cylindrical inner surface, the inside diameter of the ring being uniform and substantially equal to the outside diameter of the pipe, said cylindrical inner surface is positioned to overlie said cylindrical portion and said shoulder thereby to compress the bulge against said shoulder and seal the pipe to said connector body, the inside diameter of the ring remaining uniform after installation. 2. A flexible pipe and connector assembly, as in claim 1, wherein said cylindrical portion has a length substantially longer than the height of said transverse shoulder. 3. A flexible pipe and connector assembly, as in claim 1, wherein said cylindrical portion has a diameter slightly larger than the diameter of said frusto-conical portion narrowest portion. 4. A flexible pipe and connector assembly, as in claim 3, wherein said cylindrical portion has a diameter slightly larger than the inside diameter of the pipe. 5. A flexible pipe and connector assembly, as in claim 1, wherein said shoulder includes a radial surface forming a peripheral edge with said widest portion. 6. A flexible pipe and connector assembly, as in claim 1, wherein said connector body includes a threaded portion adjacent said cylindrical portion. 7. A flexible pipe and connector assembly, as in claim 6, wherein said threaded portion forms a flange at a juncture with said cylindrical portion. 8. A flexible pipe and connector assembly, as in claim 1, wherein said connector body is made of plastic. 9. A flexible pipe and connector assembly, as in claim 1, wherein said ring is made of plastic. 10. A flexible pipe and connector assembly, as in claim 1, wherein: a) said ring includes an outside cylindrical surface; and b) a rib disposed around said cylindrical surface between opposite end portions of said ring. 11. A flexible pipe and connector system, comprising: a) a connector body for coupling to the flexible pipe; b) said connector body including a frusto-conical portion and an adjacent cylindrical portion, said frusto-conical portion tapering from wide to narrow into the pipe; c) said frusto-conical portion having its widest portion adjacent said cylindrical portion and having a diameter greater than the diameter of said cylindrical portion and forming a radially extending substantially transverse shoulder with said cylindrical portion to force the pipe to form a bulge around said shoulder; d) said frusto-conical portion having its narrowest portion with a diameter slightly less than the inside diameter of the pipe thereby facilitating insertion of said frusto-conical portion into the pipe; e) a solid ring without radial holes, said ring having a cylindrical inner surface, the inside diameter of the ring being uniform and substantially equal to the outside diameter of the pipe, said cylindrical inner surface is positioned to overlie said cylindrical portion and said shoulder thereby to compress the bulge against said shoulder and seal the pipe to said connector body; and f) a tool including a holder for holding said connector body and a sliding member for pushing said ring onto said connector body, thereby to position said ring to overlie said cylindrical portion and said shoulder. 12. A flexible pipe and connector system as in claim 11, wherein said tool further comprises: a) a base; b) said holder is secured to said base; c) a guide operably secured to said base; d) said sliding member is slidably secured to said guide, said sliding member including a vertical face for engaging an edge of said ring; and e) a lever for moving said sliding member toward said holder and pushing said ring onto said connector body. 13. A flexible pipe and connector system as in claim 12, wherein said holder comprises: a) a bracket secured to said base, said bracket includes a first top surface having a first half-cylindrical depression; b) a first member pivotably secured to said bracket, said first member having a second half-cylindrical depression on a first bottom surface facing said first top surface, said second half-cylindrical depression being complementary to said first half-cylindrical depression; and said first and second half-cylindrical depressions are adapted to receive and hold said connector body while said ring is being pushed by said sliding member. 14. A flexible pipe and connector system as in claim 13, wherein said sliding member comprises: a) a sliding base member secured to said guide, said sliding member includes a second top surface having a third half-cylindrical depression; b) a second member pivotably secured to said sliding member, said second member having a fourth half-cylindrical depression on a second bottom surface facing said second top surface, said fourth half-cylindrical depression being complementary to said third half-cylindrical depression; c) said third and fourth half-cylindrical depressions are adapted to encircle the pipe; and d) said sliding base member and said second member include said vertical face. 15. A flexible pipe and connector system as in claim 14, wherein said first and second members are connected to each other. 16. A flexible pipe and connector system as in claim 12, wherein: a) said lever includes a handle pivotably connected to said sliding member; and b) an arm pivotably connected to said holder and an intermediate portion of said handle such that pulling or pushing on said handle causes said sliding member to move toward or away from said holder, respectively.
