The invention relates to attachment means for adjustably mounting a resistor (9) in a sealed casing, and is primarily intended for use in conjunction with start-up resistors in high power switch-gear, wherein the start-up resistancce is comprised of two mutually spaced resistor blocks which can be mutually coupled by means of a contact rod. The distance between the resistor blocks can be adjusted so as to adjust the start-up time of the start-up resistor. According to the invention, the attachment means is constructed to enable axial movement of one resistor block (9), by virtue of its attachment element being connected by screw threads with a casing cap or cover (14), so as to enable the longitudinal position of the resistor block to be adjusted by screwing the attachment element in or out. A sealing means is provided at the attachment element lead-through in the cap (14), such as to maintain the casing interior hermetically sealed. The position of the attachement element (13) is fixed by means of locking means (22).
