ABSTRACT:
A connection device for fitting to a member, particularly to a corrugated flexible pipe (146, 246, 446) formed with a series of spaced annular grooves, the device comprising first and second tubular bodies (10, 11) coupled together, in use, with the pipe received in an open end of the first body (10). The first body has a plurality of resilient lugs (14) with respective inwardly directed projections (17) at the ends thereof to be received in one of the said grooves to grip the pipe. The two bodies can be relatively angularly moved between a neutral position of the device, where the pipe is retained by the resilience alone of the lugs, an unlocked position, where the lugs are released from the pipe, and a locked position, where the lugs are forced into locking engagement with the pipe, movement of the lugs being controlled by cam formations (29) extending from the end surface of the second body (11). In other embodiments the bodies can have a rotation lock in said locked position and/or neutral position, and/or a lock to prevent outward movement of the lugs when the bodies are in the locked position.
