1. An electronic add-on module configured to be releasably attached to a drug delivery device, the electronic add-on module comprising:
a housing defining a first longitudinal axis;
a gripping portion comprising:
a first gripping ring defining a first ring longitudinal axis parallel to the first longitudinal axis of the housing, the first gripping ring being retained in the housing such that the first gripping ring is shiftable in a first direction perpendicular to the first longitudinal axis of the housing from an open condition in which the first longitudinal axis of the housing is a first distance from the first ring longitudinal axis to a clamping condition in which the first longitudinal axis of the housing is a second distance from the first ring longitudinal axis, the second distance being greater than the first distance; and
at least one spring configured to bias the first gripping ring into the clamping condition; and
an actuator for operating the first gripping ring between the open condition and the clamping condition.
