Abstract

An optoelectronic sensor device includes a waveguide element for affixing to a transparent pane on one surface and connected to a housing by way of latching barbs provided on U-shaped arms which engage corresponding recesses in the waveguide element. Slide-like locking elements are guided by the housing, parallel to the waveguide element and the pane, into the spaces defined by the U-shaped arms to prevent the arms from disengaging their respective recesses. The locking elements are adjustable by way of a handle which is flush with the housing when the latching elements are in their locked position. The locking elements include dome-shaped protrusions which cooperate with an edge of the housing to secure the locking elements within the housing.
