Please, see attached image.
I already, tried bwmorph(img,'bridge'); but it couldn't connect the detached lines.
I don't want to use extreme values of imdilate() since then the original shape and direction of the lines is lost. With extreme values of imdilate() I get thicker lines and this is not something I want to. I want to retain the same thickness but to get them elongated in a way so they can connect.
Any advice please?
Thanks

I tried using
se=strel('line',h,v);
result=imdilate(binary_image,se);
After that
use imerode (different structuring element), may be you will get similar to the original shape, with reaching the almost equal thickness.

Yeah. The small gaps filled. However there is a big gap at the upper curve that when I use high values e.g. 45 or 55 for horizontal and 14 for vertical in order to bridge the big gap, they usually tend to lose their shape and direction.
