A push fit attachment for connection to a pipe A push fitted into the attachment, the attachment comprising an outer tubular cover open at at least one end to receive the pipe and containing a grip ring 20 to grip the inserted pipe. The grip ring 20 has a cylindrical rim 30 and an annular array of teeth 34 in which each tooth 34 extends generally radially with respect to an axis of the annular array and with circumferential spacing 36 between adjacent teeth. Each tooth has a radially inner tip 44 comprising an edge 46 extending generally circumferentially, and the annular array is disposed in a generally frusto-conical array with a narrower end of the frustum of cone facing generally along a direction Z of insertion of a said pipe A through the grip ring from the open end of the cover. Within the frustum each tooth 34 has a main surface 42 facing in a general direction towards the open end of the cover. Each tooth has a said edge 46 comprising first and second longitudinal edge portions 48, 50, 54 and two points 60, 62 at an intersection of aforesaid edge portions. The second edge portion 54 forms a side of a scallop shaped notch 54 in the tooth at the tip 44 thereof and extending into tooth material radially outwards beyond each point 60, 62. At the tip 44 the tooth 34 is formed so that the points 60, 62 each extend out of said main surface 42 such that the point faces or points in a pointing direction 64 or 66 inwardly of the ring. The pointing direction 64 or 66 has a component of direction 68 opposite to the direction Z of tube insertion such that each point 60, 62 tends to dig onto a said tube A when an attempt is made to withdraw the tube in the opposite direction to Z when the attachment is in use.
