The invention refers to an arrangement (1) comprisinga terminal box (2) accommodating a pump control, an electronic extension module (3) extending the pump control by at least one additional function, and at least one locking element (11) for securely holding the module (3) at the terminal box (2). The locking element (11) is slidably accommodated within a cavity (12) and can be moved tool-less from a first position to a second position and removed from said second position to said first position by means of a tool. The locking element (11) has, at a first side (11b), a resilient latch (13) engaging with either a first recess (15) at the terminal box (2) keeping the locking element (11) in the first position, or a second recess (16) at the terminal box (2) keeping the locking element (11) in the second position. Furthermore, the locking element (11) has, at a second side (11c), at least one projecting bar (17, 18) to give free way for plugging the module (3) in the first position, and to arrest the module (3) in the second position. The module (3) comprises at least one pillar (20, 20a, 20b) extending from the base plate (7) and being insertable through an opening (21) into the cavity (12) when the locking element (11) is in the first position. The pillar (20, 20a, 20b) has a notch (24) for engaging with the bar (17, 18) in a form-fit manner, when the locking element (11) is in the second position.
