Probably not the way to do it, ... but you could do this:
def main():
import os
import glob
fldr_user = os.path.join(os.path.expanduser('~'), 'AppData\Roaming\ESRI')
lst_desktop = glob.glob(os.path.join(fldr_user,'Desktop*'))
fldr_desktop = sorted(lst_desktop)[len(lst_desktop)-1]
fldr_catalog = os.path.join(fldr_desktop, "ArcCatalog")
print fldr_user
print fldr_desktop
print fldr_catalog
wildcards = ['*.sde', '*.ags', '*.wms']
for wildcard in wildcards:
print wildcard
lst_conn = glob.glob(os.path.join(fldr_catalog, wildcard))
for conn in lst_conn:
print conn
if __name__ == '__main__':
main()
In my case with 10.3 installed at home it returns this:

There are probably more searches (wildcards) you could include.
