Abstract

There is provided a pipe joint (2) comprising at least one connection end wherein the or each connection end comprises: a wall defining a receiving recess (8) for receiving an end of a pipe length (4); a tapered locking recess (26) formed in an internal surface of the wall and containing a correspondingly tapered locking element (28); a through hole (20) in the wall which communicates with the tapered locking recess; and a fixing element (30) rotatable within the through hole and formed with a foot portion (30c). In a first unlocked rotational position of the fixing element the foot is at least partially retracted from the locking recess; and in a second locked rotational position of the fixing element the foot extends into the locking recess to urge the locking element between the tapered locking recess and a pipe located within the connection end.
