A connector kit for connecting a first apparatus to a second apparatus, said first apparatus having a first female connector jack, and said second apparatus having a second female connector jack, said kit comprising: an electrical connecting device comprising: a first connector and a second connector arranged at opposite ends of said connecting device, each connector (11, 12) being adapted for connection with a respective one of said connector jacks, wiring electrically connecting said first connector to said second connector, wherein said first connector and said second connector each comprises a male connector plug (11, 12), said wiring has a length (L w) between said first and second connector plugs (11, 12) which is shorter than a length of each of said connector plugs (11, 12), said wiring is enclosed in an enclosure of an elastomeric material providing an elastic deformability to said electrical connecting device, characterised i n that said connector kit further comprises: a guide sleeve having a first open end and a second open end, said electrical connecting device being insertable in said sleeve such that said first connector plug faces said first open end and said second connector plug faces said second open end, said sleeve being attachable to said first apparatus such as to surround the first connector jack, said sleeve being insertable in a recess of said second apparatus, said electrical connecting device is movable in said sleeve, said enclosure comprises a flange extending radially outwards from a longitudinal extension of said electrical connecting device, and in that said flange has an outer circumference which is slightly smaller than an inner circumference of said sleeve. an electrical connecting device comprising: a first connector and a
