Morphology
There is a clear metaphorical link: a 'spanner' (tool) inserted into something suggests causing a malfunction or obstruction, so a learner who knows the words might infer an obstacle to a 'plan'. However the expression is a conventional idiom (often 'spanner in the works') and the specific idiomatic sense is language- and culture-bound and not fully predictable from the parts for a B1 learner without prior exposure.
Etymology
Spanner in the plan may come from the picture of someone throwing a spanner (a wrench) into a machine so its parts stop moving, ruining the plan. So it means 'an unexpected problem' that stops what you planned.
