Stop collar attachment

An assembly of a function element, pipe attachment device and pipe, the assembly comprising:

• a pipe attachment device provided around a pipe and attached to the pipe;
• and
• a function element provided around the pipe and connected to the pipe attachment device;
• wherein:
• the pipe attachment device comprises one or more recesses on its outer surface;
• and
• wherein a length of each of the recesses on the outer surfaces of the plurality of fingers is substantially the same as a length of a part of the function element that is retainable within the one or more recesses so as to prevent axial movement of the function element along the pipe.

A method of connecting an end part of a pipe attachment device to a part of a function element, the method comprising:

• aligning the longitudinal axis of a substantially tubular end part of a pipe attachment device with the longitudinal axis of a substantially tubular part of a function element;
• applying a force that moves the end part of the pipe attachment device and the part of the function element relatively towards each other along the longitudinal axis so that the contact between the end part of the pipe attachment device and the part of the function element causes each of a plurality of fingers on the end part of the pipe attachment device to elastically deflect;
• and
• further applying the force that moves the end part of the pipe attachment device and the part of the function element relatively towards each other so that each of the plurality of fingers on the end part of the pipe attachment device returns from their deflected position and is retained in one or more holes or one or more recesses in the part of the function element,
• wherein the end part of a pipe attachment device is a part of a stop collar;
• and wherein the stop collar is a two part stop collar with the stop collar being attached to the pipe by the two parts of the stop collar being press fitted together.
