A well screen assembly has a base pipe (14) and one or more screen sections (18a-b) attached to the outer surface of the base pipe (14). The assembly also has one or more shunt tubes (530a-b) attached to the base pipe (14) via top and bottom rings (20a-b). The shunt tubes (530a-b) can be attached to the screen sections (18a-b) via B-rings and may be transport tubes or packing tubes. Connections (500) are used for securing a jumper tube (540) to adjoining shunt tubes (530a-b) of adjoining screen sections (18a-b) of the wellscreen assembly, which may be used in open or cased holes. At a well site, the joints (12a-b) of the wellscreens have timed threads so that the various shunt tubes (530a-b) can be aligned with one another along the assembly as the joints (12a-b) are made up. The connections (500) of the present disclosure allow operators to install a jumper tubes (540) between shunt tubes (530a-b) at the joint without needing to tighten fasteners or assembly components.
