Abstract:
1. An annular collet radially located within a coupling assembly for connection of a pipe thereto, said coupling assembly having a hollow body, an internal abutment surface disposed inside said hollow body, a nut having a hooked projection that extends into said hollow body when engaged, and an annular seal that abuts against said abutment surface, said collet including: an annular rearward portion, which includes a surface generally parallel to an inner surface of the body which permits this portion to slide into the body such that the rearward portion abuts against said annular seal, and a forward portion which includes a plurality of radially deformable barb sections as gripping means to grip the pipe; said annular rearward portion including at least one split extending generally axially there along, said at least one split defining corresponding first and second generally parallel ends of said collet rearward portion, said generally parallel ends abutting one another; said rearward portion first end including at least one substantially circumferentially extending projection which engages a correspondingly shaped cavity associated with said rearward portion second end, thereby preventing or at least minimising axial movement of one of said rearward portion ends relative to the other.
